Well guys, I just got my first “proof” the E-M1 will indeed get 4K video recording via firmware upgrade! I got an image I cannot share showing the video settings of the E-M1 with the new firmware. I can tell it really doesn’t look like a fake image or so!
It shows “mov 3840×2160” in the settings. And framerates were 25 + 30 + 50 + 60 + 120 + 240 in movie menu below Mode function.
The story is really strange. Seems like only a small group of testers got the 4K feature in their beta firmware while other “photo” testers didn’t have this. That could explain the contradicting rumors I got. I have been told the firmware is coming on Sept 14 or Sept 15. For the first time I really believe that 4K is coming to the E-M1…I saw it 🙂 That’s going to be a very bold move by Olympus. Adding 4K to a camera via fw update is something none has ever done before. Chapeau!
UPDATE: I still have sources saying they don’t know about 4K on the 2.0 firmware they tested or saw. So either this is a super secret Olympus addition or Olympus will decide to not add the 4K feature on the new firmware. This is one of the weirdest rumors I have ever worked on. I am glad this will be over in a few days 🙂

This is really odd. I’m glad I ordered my EM-1, either way. I’m not getting excited until the firmware is officially released. Fool me once…
Yep, I’ll also believe it when I see it. Happier about the new framerates than the 4k if true.
If true, I have some major upgrading to do, new SD cards and prob new iMac to handle it!
Wait what?! From “probably not true” to ” hah, knew it” to “what wha?” This firmware rumor has been a roller coaster ride.
I’ll just wait and see. There have been too many contradictions in this story so far to do anything else but simply wait to see what actually materializes.
no 4K, the picture you saw was probably just from a testbed EM1 for new OLY cameras
That would explain a lot
Not really interested in 4k but would love 240fps, even at 720p.
240fps would be in 240p like Olympus has in their pocket cameras, and for some reason advertises their E-P5 to be able to do that. But that video has been removed from Youtube after being there over a month (highly because false advertising, as it was old video for their pocket cameras).
720p would get 120fps. That is more than enough. It looks good enough, especially if sharing on web. But can be fancy effect in limited situations (like throw 2×2 grid of different angles of 240fps and it doesn’t look bad)
https://www.youtube.com/watch?v=FJDz4NZyVVQ
Olympus does have industrial high speed cameras that gives 2000fps at full resolution (1280×1024) and with smaller resolution a much higher frame rates (up to 1 million).
http://www.ix-cameras.com/
http://www.ix-cameras.com/gallery.php
Only uses I would find for 4k myself is that I could sometimes pan the view shot with 12-40mm at 12mm in different events. Or if really in bad situation, maybe stabilize the view more (typically means the video gets blurred altogether already).
I thought I read somewhere that Olympus sold of the high-speed video business , ah found it while typing
http://www.olympus-ims.com/en/hsv/
Not sold off, but transferred, sort of….
“Using staff trained at Olympus, iX Cameras is now responsible for servicing all i-SPEED cameras. In addition, i-SPEED 3 series cameras will still be manufactured at Olympus to the same legendary quality standards that have become synonymous with the Olympus name.”
http://www.ix-cameras.com/company/about-us.php
If true , definitely will cheers EM1 owners up .
But I believe no everyone need 4K especially those who don’t play around with video recording like me .
Yes. But it would make the m4/3 “tent” bigger by making it more attractive to us who use video. A bigger tent benefit all m4/3 users.
If that works out to be true, this might be nice. But Arri’s success in the video market should really tell Olympus that 4K isn’t the be all, end all for video, dynamic range, bit rate, format, workflow, etc. are all just as important.
Other improvements such as keystoning are nice additions too, but here I’d question Olympus’ sense of priorities : are a few additional art filters more important than at least catching up with Nikon regarding auto ISO implementation, for example, or improving the frame rate with peaking, or adding exposure compensation in manual mode, etc. ?
Exposure compensation in manual mode? Too funny!
The rest of your comments are equally flawed.
Clearly you haven’t noticed that Olympus allows you to use auto ISO in M mode.
I think they get that. The problem is that you have no form of exposure compensation in manual mode once you put it in auto ISO, beyond changing aperture/shutterspeed. You can’t just dial in a stop of compensation and let the camera adjust via ISO. If you did, it’s probably how I would shoot 90% of the time. Sure you can change your metering method, but it would be better to just dial in compensation as usual and not think about it.
It’s ‘Manual’ mode – the idea of ‘automatic compensation’ is an oxymoron to me. It sounds like you want a manual mode that is really another auto mode, where the ISO is a variable set by the camera.
I don’t get why you would even enable the Auto-ISO option in Manual mode via the menu anyway. If you want to vary the exposure via the ISO, you can just do it Manually by flipping the lever to 2 (if you are using the default) then just adjust the ISO to vary the exposure using the front dial.
First we had bitching about no focus peaking, then when it’s provided we get bitching about the frame rate or the colour of the tell-tale. I have focus peaking on the fn1 button and just enable it to focus then disable it if the frame rate bothers me. Faster would be nicer but I’m not going to toss my E-M1 out of the pram if it doesn’t get it.
Clearly I wasn’t talking about ISO at all, I was talking about exposure ‘compensation’, which to me means adjusting either the aperture or shutter speed at variance from the meter designated optimum.
Not funny at all.
Shooting Manual with Auto-ISO is on of the best things when working with Olympus Cams. It’s the mode that is missing in the analog „PASM“ concept, allowing you to control the parameters that shape your image directly. Disabling exposure compensation in this mode is seriously limiting right now.
Frame rate with peaking hopefully also gets addressed, some reports point in that direction.
Such filters are developed for the entry level cameras so it’s not really taking away from the efforts they spend on the pro grade cameras. It’s more like “we have this already done (PL7) so why shouldn’t we give that feature to all users”. I like the philosophy and think it’s positive that the Olympus cameras are almost the same from the software.
Interesting if true.
Would the camera deactivate the 5 axis and use 3 axis stabilisation instead in order to reduce the heat on the sensor?
Olympus could be pressured to do this considering that Fuji on its X100t is offering 24,25,30,50 and 60P for the first time.
Good question. We’ll find out soon I guess.
No. The sensors on the E-M1 and E-M5 are held in place by magnetic fields when in use. The IBIS doesn’t add much, if any heat at all. It is essentialyl always on I think, except when you hear the clunk when it gets physically parked and the levitation is turned off
Some people thought that you couldn’t adequately heat sink a floating sensor because it isn’t attached to enough material to dissipate the heat and they thought that doing video or 4K heats up a sensor, but others rightly pointed out that live view, etc, show that readout of the sensor doesn’t cause more heat because the sensor is essentially on all the time. The heat seems to mostly generated by the video processing/encoding hardware which is most likely on the motherboard which can be better heat sinked.
Good to know. Thanks
But does live view read out the whole sensor just like a normal video or image capture, or just parts of it. Or in a different(lower IQ) less taxing way. That could make a huge difference in terms of sensor generated heat.
What happens to the sensor when you take a 30+ minute single exposure?
I want to believe.
😀
I’m just tire of these articles.
“E-M1 has 4K!” click.
“Sorry, E-M1 doesn’t have 4K!” click.
“Surprise! E-M1 will have 4K!” click.
“Update! E-M1 will not have 4K.” click.
“No really, the E-M1 will include 4K!”
interesting! I will just take a wait and see viewpoint at this time. The EM1 is a great camera as it was released. If they can improve the movie functions in any way via firmware all the better. I’ll remain cautious on this one. A lot will depend on if any problems were found in the testing. Only a few days, I will wait and see. 60p with a decent codec and bitrate would seal the deal for me. Every thing else is just a bonus. But even if none of this is true, the EM1 remains on my wish list. Like I said, a great camera as released. Any improvements are just additional benefits. A decent movie codec of any kind would help close the deal though.
Well, definitely good new for em-1 owners, if true… Holding excitement… Wel’ll all see and know very soon by the beginning of next week.
Can’t say I’ve shot video much with my e-me, but adding 4k + additional frame rates is always welcomed. Surprise no 24fps… Pretty certain if we do get this update, 24fps will be included. Fingers and toes crossed.
Couldnt’t care about 4 K ….will mean super heating your sensor …Why ?? Just take photos ! Leave video to bsspoke video cameras ! I want the 40-150 NOW (to take stills !)
Why, if you do not shoot video then your sensor would not heat up. I don’t think suddenly by adding 4K with firmware your IQ on your still would be worse.
Agreed! What I mean is I don’t care much if they do to add 4k . I imagine users of 4k will need some serious SD cards too and powerful computers. I’d much rattler if Olympus put resources into developing the OMD system into a professional system quickly. I’m not impressed with announcing lenses 18 months before delivering them !
“Super heating your sensor”
Oh well…. does people still fall for that?
GoPro 3+ Black Edition, capable to 4k at 15fps and 2.7k with 30fps.
https://www.youtube.com/watch?v=HwvixZiufdk
That camera is way smaller than any m4/3 camera body is, it is closed in small plastic weather proofed cases (no air in/out, no heat dissipation at all!) and people shoot 1080p 60fps for hours! WITHOUT HEAT PROBLEMS! https://www.youtube.com/watch?v=hOA7Aq5pXDc
The source for the heat in digital cameras is the CPU and battery. Just like now if you record E-M1/E-M5 1080p video for hours (just re-start after 29:59:59) you don’t get problems, even when shooting in higher environmental temperatures than 21 degrees.
Do you know what is currently the Olympus main competitor for video? (Or m4/3 system all together?) It isn’t Canon, Nikon or Panasonic.
It is the smartphones. When Nokia released their Nokia 808 Pureview it launched the competition. Then Lumia 920 with the OIS was good enough for many (still weak OIS level). But now when Nokia has off from smartphone markets and Microsoft doesn’t succeed, Apple strikes and it does strike hard. IPhone 6 Plus with the OIS.
https://www.youtube.com/watch?v=mZknw29tCiw
THAT is the thing what people will turn now on when they start talking about OIS/IS. Not Panasonic, Canon or Nikon and not Olympus. Even when Olympus has best IS on the markets, they are sleeping giant that could crush the video markets. Do what Sony/Canon did with camcorders by miniaturizing their sizes from bulky size so you can carry one in your pocket. https://www.youtube.com/watch?v=JWd1HuKubJ4
The smartphones (as well obviously mentioned by Schiller for Apple fans) have replaced pocket cameras and camcorders. There is huge market among teens and others who want to record their activities like skateboarding or snowboarding etc. And they want stabilization. For them Olympus could have offered something amazing with 50/60fps and 25fps modes (for countries that have 50Hz electricity grid and slow motion possibilities). No 4k is required. 24Mbits bitrate is already over required high quality one.
Now Apple comes with good stabilization system (and more likely doesn’t do same stupid Ad mistake what Nokia did https://www.youtube.com/watch?v=PbF7TgX9gy8
Now the question is, has Olympus waken up and offer something improvements (those framerates 25-240 sounds great) or does it sleep forever? As Olympus should protect m4/3 system as Panasonic can’t do that. Panasonic doesn’t have the IBIS what Olympus has.
The m4/3 system can’t compete with other market segment that GoPro has conquered, the serious sport peoples hearts (I don’t own GoPro, never will) as you can so easily attach the camera almost anywhere from airplanes to helmets and bikes/cars etc and get 1080p 60fps (and in future 4k with 30fps, 1080p at 120fps and 720p at 240fps! http://dgise.com/post/62262921573/gopro-hero-4-specs-and-release-date-are-disclosed).
Sony is doing little bit similar thing with their own fancy camera for smartphones. A video recording in size of almost the Olympus 25mm f/1.8 objective. WiFi control etc. Does Sony have problems with heat? NO! That camera can offer great features for person who can think more out of the box.
Smartphones today have started to get 4k videos. A small tiny camera in very small tight weatherproofed body and without heat problems. Quality being far better than people really need or care.
How long does people still talk how sensor will heat up?
In photography we can do long exposures, sensor is all the time ON that period. Full frame is capturing photons whole time, not just doing 30 second exposure but we can do 30-60 minutes or even couple hours. We can take series of long exposure shots without problems that camera is forced to turned off because sensor heats up.
But what doesn’t happen with long exposures, is that CPU and so on Battery doesn’t heat up.
The problem is how to get CPU and Battery generated heat out of the camera. GoPro manages to do it with tight weather proof case made from plastic, where temperatures doesn’t raise too much (some cases at 125F the camera is turned off).
1) Olympus needs to protect m4/3 system against smartphones with their IBIS
2) Olympus needs to protect their share from m4/3 system.
3) Few engineers working with video firmware at Olympus, doesn’t mean their time is off from engineers who work for stills. It is teamwork where different people work different parts on whole process and if it is done well, they can work parallel and other process doesn’t affect to another.
Just like rumored, video people have on schedule and progress and if they manage to improve video, it gets implemented.
Now we can only imagine and think what those photos were, were they from test camera or from stock camera and does the features get to 2.0.
The firmware what was found from Olympus servers has been removed quickly after it was shown. (in few hours, people at Olympus follows 43rumors!) and as people said, flashing it told that it was 1.5 and not 2.0 in software (AFAIK). But in camera it told it was 2.0. So it is possible it was unfinished 1.5 firmware (or ready already!) and not the real 2.0.
Jump from 1.4 -> 2.0 is HUGE. You need more than few new art filters and live composite. The rumored features were that the EVF gets improved by refresh rate and the filters speeds gets improved.
Well but what? The testers who flashed the “unofficial 2.0” with LightSnowDev tool doesn’t show ANY such improvements. No real improvements to functionality, just couple art filters and live composition etc.
And when it comes to firmware developing, it is done to last minute. There can be even engineers working on firmware when it is announced on Photokina until in last minute it is uploaded to servers (or if they release it only later).
I would not want to be any of those engineers because I know when the release date gets closer, less sleep you get. Been there, done that, NO THANKS! In last week you can maybe get one or two hour sleep a night and last day you go without.
If Olympus managed to get improved video for m4/3 system protection, it helps everyone. Those who want 4k and want 200Mbits can go to Panasonic then.
Skilled people can work with E-M1 even on current state now, but not even they can work around the 30fps limit on 50Hz electricity grid as that framerate causes light flickering. You can only minimize it by shooting at 1/50 shutter speed or 1/80 (IIRC) but every indoor or outdoor video with lights is ugly.
And THAT is the unacceptable thing from Olympus. 30FPS is great otherwise, no need for 24FPS or even 60FPS but if they just would give the 25FPS so possibility use video camera elsewhere than under natural light would be HUGE improvements.
So if you live in country that has 60Hz electricity grid http://en.wikipedia.org/wiki/Mains_electricity_by_country#Table_of_mains_voltages_and_frequencies then you can be happy for current video. But rest of the world can’t be as now when darker times comes again, more lights are required and that renders E-M1 unusable.
Well, that was certainly an impassioned response! 😉 🙂
If it’s true, then this update shows Oly’s development scheme is truly suicidal for their sales. TruePic VII did not show better video performances than TruePIC VI for year. If processing 4K on TruePIC VII was mechanically possible, Oly could add better 1080p when E-M1 has released. It only means that Oly had great DSP however they did not tried to utilize it for a year – truly deceitful.
And what if the other sources saying that they were not ready? It was better to release camera with already stable/good video than push camera release further (6-12 months at least!) and lose sales with that, more likely customers from 4/3 system etc!
If video isn’t the priority, it doesn’t mean they don’t care about video. It only means that they get other features first and then later they can improve other secondary features.
If hardware is there, then it can be locked with software. If it is locked with software, then it can be opened with a software.
Why doesn’t people whine about Panasonic and Canon doing ***** things for their customers? Look what hackers managed to do with GH2! Why didn’t Panasonic unlock the higher bitrates and framerates but hackers were required to do that!
Why Canon doesn’t improve their videos but again hackers are required to do that?!
Why Olympus is the one that gets truckloads of ****** from doing exactly same thing as Canon or Panasonic?
Deceit? Are you a crazy person? They sold the camera with the listed features, all working. I don’t think you know what these “words” are that you are trying to use.
Pics or it dind’t happen.
Admin has the pics…. As told, can’t release them.
I still don’t believe the 4K bit. However, PAL frame rates should have been provided from the start and I hope Olympus gets to its senses.
I agree with you. PAL frame rates should have been there all along on all cameras!
Still no new firmware for E-M5… Shame on you, Olympus!
For what exactly…E-M5 is a more then 2,5 year old camera(technically limited), and works fine. Oly has released a new firmware not too long ago, even adding new features.
The Em5 currently has no replacement, so technically it is still in production and selling well, so updating a model that is cheaper to make is very attractive for , Olympus, also what we want in the EM5 firmware update is focus peaking, better video codecs, so it is not such a crazy request, and one can dream right?
Hardware limitations. The art-filter focus peaking hack shows that E-m5 can not keep up. Even E-M1 show a little lag here and there with peaking enabled.
And although E-m5 does not have a direct replacement, I tend to think the gab between E-M10 and E-M1 is too small for an extra OM-D model.
E-M10 is kinda like an upgraded E-m5 without weather sealing and a very small IBIS difference. And if you want added (battery)grip, then E-M1 is the alternative.
i don´t care if it lags, i just want it, the focus peaking is meant for using manual lenses and i am already taking a lot of time to get things in focus, a little bit of lag won´t hurt no one, but peaking sure is going to make me happy
Shoot RAW and shoot using ART filter Keyline. That will give you A sort of focus peaking and a file that is unaffected by the filter.
yeah i tried that, it didn´t work out for me, maybe another…
Sold if true, not interessted at all if not.
Please be true, please pretty please!
These E-M1 firmware update rumors are a emotional rollercoaster ride 🙂
Isn’t the firmware allready available without the update tool ? Didn’t anyone flash it somehow allready ?
The pre-release firmware turned out to be an old beta (v1.89 if the reports are correct).
It got pulled off…..
Olympus could get a huge recognition If they somehow are able to add 4k with a firmware update. Not to mention completely redeem their lack of video options so far.
I thought they would put the 4K to their new EM-2, then it can be the selling point for the next model, right!!?? haha… But anyway, they didn’t do a very good job on 1080p video quality anyway. So I don’t expect to see a very amazing 4K output from the camera itself. But surely, the 5 axis image stabilization is awesome for video shooter. I wish they had it on Panasonic GH4 🙂
1080p is pretty good to me
I begin to believe the story that they went in to heat issues so this screen could be from the beta firmware that existed but ran into heat problems while recording 4k. Maybe they stripped the video features out for the upcoming firmware for safety reasons and bring the other video features (beside 4k) back at a later point?
That would be my guess. At least we can be pretty sure that Olympus is working on such things, whether we’ll get it with the E-M1 or a new body with more cooling elements. I might be completely wrong, but this sounds plausble to me and would explain all the forth and back with the beta firmwares.
Maybe.
PhotoReview did an interview with Olympus personnel with Toshiyuki Terada with this last paragraph applying to this now.
“Mr Terada added that Olympus is seeing increasing demand for expanded video capabilities, including increased frame rates and better sound recording. 4K video is also showing up as a potential demand, although Olympus will not move into this area until there is an agreed technology standard. Most camera buyers, he says, want video included, even though they may only use it occasionally.”
See the whole review here. http://www.photoreview.com.au/stories/general/olympus-designers-speak
I bought the e-m1 for stills, as I travel a lot and my old 5D was too chunky and the primes annoyed me… The e-m1 with the 12-40 2.8 and the promised 40-150 2.8 where the perfect solution for me. Now using a mirror less, I recognized, that shooting video sometimes is really nice. Improving the video would make me really happy (even though I really do not need 4k as I am not familiar with downscaling it or any of that “pro stuff” you can do)! 1080p with more frame rates and maybe 120 fps with 720p would make me as happy as I could possibly be. I bought a perfect camera for me a year ago and now my camera gets even better without spending a dime!
I really do not understand people complaining… The e-m1 is, with its obvious limitations due to the smaller sensor (especially compared to FF), the best mirrorlless camera available… (at least for me)
Totally agree. Just a few years ago we haven been used to two companies that put every tiny update in a big paid upgrade (new camera). We should be glad that Olympus, Panasonic and Fuji follow a different philosophy.
Don’t know if it has anything to do with this rumor, but apparently Olympus had a strong video development team in-house until very recently.
Read here:
http://www.ix-cameras.com/connection.php
One sentence that caught my attention:
“The two companies will continue to share information, resources and technology.”
won’t happen…but for all you who want to shoot tethered…your wish will be granted
yuor explanation of different models for different test groups sounds somehow convincing admin..but as usual, if true, we wont get rid of any complaining here, not even with those added framerates.
+1000
True story. +65535.
So true. 😀
Will be an optional paid-for uipdate
…and the lens hood for 4k will cost $80. 🙂
Now wouldn’t everybody be peeved if it was only for the silver E-M1 (as Mk II). 😀
everybody is talking about the 4k firmware upgrade and seems to forget that the actual problem is not the 4k resolution. The real problem is the chubby codec and the bitrate. So, instead of just adding 4k they should add 24p, a better codec, more megabits for bitrate, and a sort of prores so we cand have a good colors correction in post, this we’ll be bold and we’ll have me sold.
I think that’s an impossible combo. Well, some of it. There’s got to be a bottleneck in the hardware preventing the transfer speeds. You can’t fix everything in software/firmware. But yeah, if they can open the througput enough, maybe in tethered mode?
Indeed, oly has never shown Video potential. adding a 4k option doest make it automaticly a good video camera in any way.
and its unlikely they can add 4k support by firmware, or they must have been working on it from the start making at hardware capable, and introduced the em1 sooner so they could work longer on the 4k firmware.
anyway:
the gh4 is much more video oriented, peaking, DFD, ntsc/pal support, high bitrate, all intra, luminance curves, it has al the software a video maker can wish for.
Oh yes, GH4 has all of the above and 5-axys IBIS too!!! … oh, wait….
I said software, and IBIS ain’t software
So you may be getting free 4K video added to your photographic tool, and you are already complaining that it won’t be good enough. The world would be a better place without people with your mindset. Just shut up.
By the way:
http://www.eoshd.com/2014/09/olympus-beta-tested-4k-firmware-e-m1-developing-cine-lenses/
Check the second picture closely…
If this ends up being true, maybe metabones will get it together and make the EF adapter work with the EM-1 and EM-5.
They already make an EF-M4/3 adapter….
It doesn’t work with the E-M1 or EM-5
It doesn’t mount to the body. The “prism” blocks it. Check their compatibility list on their web site.
Then they should think about redesigning the casing then. Do they want a market for them or do they think only PEN uses will want them? If they are going to make an aftermarket unit, it’s gotta fit!
Don’t forget the Panny bodies. I suspect they sell more of these to GH users than any other m43 body type, by a large margin.
Hey Oly! I have a small video shoot next Sunday.Would you please send me the FW2.0 BIN file so that I can test it? Our E-M1 owners should adopt the Apple fanboys last motto : “my body is ready!” 🙂
When shooting 4k 30fps video or heck 720/30fps video, the sensor does exactly the same thing: Sends the all 16mp pixel information for further processing at the desired rate. So if there are heat issues, I can’t follow the logic how 4k would cause sensor to heat up?
As of current E-M1 state, what you say is not true.
E-M1 is still using line skipping to conform the sensor output to each frame of video.Hence, with lower video resolution, fewer sensor cell reading is triggered by the circuit.
Only starting from Sony RX10, consumer hybrid camera starts to see whole frame reading for video (or one model before this? not sure but definitely Sony). Sony is still leading in this regard.
Then let’s say that the 4K is coming, would that mean that lines are not skipped anymore? Because if so, that could also mean better IQ for 1080, and especially so when the digital 2x crop mode is used? Now the 1080 quality is quite tolerable, but digital 2x is useless.
Sure it can use only specific lines. And in CMOS the whole row is (or column) read out as whole, unless the sensor has A/D in each pixel when each pixel is read out at once.
But even video recording does cause whole sensor being processed, but only specific rows/columns are processed. Or then it can be done that everything is readout and only compressed more. That is the fastest way than simply use hardware that would cause interlacing and aliasing very easily.
As E-M1 has same sensor as GH4, I bet that Panasonic designed sensor to do full readout that is then only rescaled. And doing the rescale is much more CPU friendly and so on consumes less watts and so on way less heat.
Just think what GoPro has managed to do https://www.youtube.com/watch?v=hOA7Aq5pXDc
Do you see a metal heat sink somewhere?
In a case that is waterproof to 60m depth (?) etc and still no problems.
https://www.youtube.com/watch?v=8crpB4YRMHY
https://www.youtube.com/watch?v=QroXo_xIXwo
https://www.youtube.com/watch?v=MwIgimBtTaA#t=142
Does someone want to tell what is their logic that why GoPro has managed to get the plastic case transmit heat better than m4/3 camera that has battery and CPU separated further?
https://c2.staticflickr.com/8/7370/12525009785_f9ae8c5341_z.jpg
With all cameras, when raising the required processing and so on battery consumption, temperatures starts raising. It doesn’t matter much what size the sensor is or what resolution it is shot.
H.264 codec has huge CPU requirement, but small when compared to H.265
http://www.extremetech.com/computing/162027-h-265-benchmarked-does-the-next-generation-video-codec-live-up-to-expectations
http://www.trustedreviews.com/opinions/h-265-vs-vp9-4k-video-codes-explained
When CPU needs to compress data to tighter, it is question about saved time, power and bandwidth.
With H.264 the benefits for higher bitrates are gone after 4-5Mbits, as codec was designed to be used between 2-3Mbits networks.
High quality Blu-ray movies are often encoded with 17Mbits bitrates and if there is space it can be encoded with 24-36Mbits but benefits are very small unless we are talking about scenes where it is crucial (dark scenes, lots of sharp details etc).
We can design a small processor that is very power efficient to encode specific codec. But we can as well make a good software algorithm to do same but in expense using a general purpose CPU in exchange for power consumption.
In digital cameras our problem is the battery and processing power.
Nice, but where is the E-M5 firmware update?!
load of bs
I wouldn’t call three words as “load”, but for some people even the little is a lot.
We see after weekend what Olympus has cooked on us.
If this is true, the move has probably been motivated by frustration only – arising from sales results. Too high a price for a small-sensor toy – otherwise not a bad one – that costs the earth but has 20% lower ISO capacity that the E-PM2, sold for FOUR times less.
Initial E-M1 price (Europe) €1500. Today, only 10 months later, one can get it for €750 from the US! Why, oh, why? Americans are nice people or what?
OK, otherwise I like that, because now I can get it from the US!
But I will get it to use my FT glass, not to shoot 4K video with a body that cannot even shoot good HD video!
Too many commercial blunders by Olympus! They should have produced a normal-priced DSLR or DSLR-like body with the powerful Sony sensor and the new stabilization. Instead, today they are acting like a magician pulling white rabbits out of his hat.
Sorry but Olympus pulls hat from the rabbit….
Does the hat have cut-outs for his whittle ears?
Poor rabbit! Poor us!
It does not have 20% less “ISO capacity”, whatever it means. If you are checking the “sports” score on DxOMark, it does not tell the whole story – check the graphs.
You can’t tell Jankoff anything – he’s a ROM-based artificial semi-intelligence with pre-built opinions and no learning capacity.
Just look: “small sensor toy”, repeated ad nauseam – yet MFT cameras today are the equal of APSC cameras <= 2011 and FF cameras <= 2007, used by pros worldwide and good enough for the likes of National Geographic.
Put him on ignore. 🙂
Who is telling me things and stories about sensors, difference in sensor generation and impact of this on lenses? I have 7 (seven) FT and mFT cameras, more than fifteen modern, incl expensive, lenses for them, old lenses and a modern APS-C with a powerful sensor. I do not know what I am talking about? If this were the case and I am a fool, why pay so much attention to what I am saying? I know why. Because you have been more or less cheated, and I haven’t.
So… you bought all that MFT gear before you Saw the Light, and now you feel cheated – or you Felt Cheated, bought it all anyway, and now spend your time here going on about toy sensors and booing Olympus?
Sorry, neither situation paints you in a very flattering light. 🙂
He feels cheated, so what? I understand. M43 is a big con my friends. When are we going to put down the fanboyism and develop some sensible consumer culture?
We’re not your friends, and how can MFT be a con when everyone can see for themselves exactly what the inputs and outputs are and make objective decisions about the results?
Why would anyone deceive themselves?
You speak of “sensible consumer culture” – which is, what, trolling forums for equipment you don’t even like and posting risible exaggerations?
Maybe you’re too narrow-minded to get why MFT makes a lot of sense to a lot of people. That’s okay, there are plenty of ignorant people in the world – what I don’t get is where your ego comes from, or what purpose you think you’re serving here.
It’s tiresome, man. Stick with what you like, and let others do the same.
Relax kid, nobody wants to take away your toy.
SNORE
No they are not the equals, and not even close. It’s amazing how much bad information there is on the internet. But don’t take my word: try yourself.
lol – you go too far; there are definitely grounds for disagreement, especially in specialized situations, but you lose all credibility by saying “not even close” – you should probably follow your own advice instead of believing things you read on the internet 🙂
Yes, whatever it means, it is an irrefutable fact that the DxOMark score for the E-M1 is (roughly) 20% lower than that for E-PM2. Had it been otherwise, say, E-M1 with a 20% higher ISO score, I would have bought it a long time ago and keep my mouth shut. As it is now, I feel morally obliged to raise my concerns. A reputable company does NOT launch a new product with a 20% lower score in a VERY important parameter and ask four times more money!
Jankoff, you are completely off your head. You don’t even understand the DxO ranking system.
Stop looking at the scores, look at the actual high ISO measures and pictures.
I still think this can’t be anything else but a hoax, but if it would be true it would be great news indeed, also for users not interested in filming. 4K isn’t just about high resolution video, it also gives you a very fast (30 fps) burst mode – you can extract very acceptable stills from a 4K movie.
Yes, indeed. Many seems not to be aware of the 8mp continuing 30fps feature.
Don’t go wetting your pants over this! Obviously a couple of testers had a 4K enabled camera to test, but I will wait & see what officially comes & if it is there I would not be surprised if it is limited to short clips only (as the Stylus 1 is with HS 120 & HS 240). That is not to be sneezed at either, but I’m waiting & not getting any hopes up, not that I want or need 4k video, but it could be useful for motion grabs though.
Would be nice to get even 30-60s with 120/240fps. Think about Olympus 60mm Macro and 240fps for bees.
Or coming 40-150mm f/2.8 Pro for 720p 120fps next to sport field/arena!
Or mount camera on tripod and do some golf training to improve your swings and brag about it to your friends by sending it over WiFi to them sitting in club bar…..
Or less energetic, learning & improving fiddle technique (yeah, I’m a fiddler). I fiddle with violins when I’m not fiddling with cameras.
This is very strange indeed. If E-M1’s FullHD quality is not among the best, it’s very strange they’d like to add 4K. Maybe it’s only for timelapse, combining 4K res stills into a clip.
I’d be happy if they brought the 1080p up to GH3 standards in regards to quality.
You do not need such thing (as I now recall that was the one rumored feature for timelapse, now being 15fps at 720p) as you do it with computer. Just record timelapse but disable the “generate movie” in menu. Then take photos to computer and run timelapse software and you get 16Mpix timelapse instead 8Mpix. And you can choose what ever ratio you want after as you use full frame, without requiring to change ratio in camera before shooting.
I have two sources telling a different story. Olympus tested a 4K firmware in a small beta group, using an EM-1. It had all the framerates mentioned plus 4K. However, some of the betatesters experienced overheating issues, shutting down the camera after approximately 15 minutes. Olympus have since decided to hold back the firmware and improve the mechanical design. The new video features will now be part of next generation hardware. Likely to be EM-2 and EM-6. So, don’t expect to see this at Photokina.
So other group of sources tell that it was tested -> concerning for temperature and other group of sources telling there never was any testing?
To me it sounds more like three or two and half 🙂
1) Done, testing, rejected until new models
2) Never done, never will
3) Done, testing, doesn’t know it will not be released
OR
4) Done, testing, believes it will be rejected until new models and doesn’t know it will be implemented as not every tester got problems.
Does E-M1 even have a temperature sensor in sensor box or in sensor?
I have not heard / read anyone seeing the E-M1 would shut down for overheating?
I have done my own testing with E-M1 in over 60 degree Celsius (that is over 140F) environment over hour without problems and IBIS enabled all the time.
So what kind temperatures we could expect from 4k? Does GH4 body get over 60 degree?
“Does E-M1 even have a temperature sensor in sensor box or in sensor?
I have not heard / read anyone seeing the E-M1 would shut down for overheating?”
Read page 139 of the manual.
” ! Internal camera
temperature is too
high. Please wait
for cooling before
camera use.”
I know it says so, but when I have not heard/read anyone experiencing it, why it is there? Not even in high temperature environments does alarm raise. Either it doesn’t work, there isn’t such or temperature isn’t a problem at all.
Page 26: “If the temperature rises further, the camera will turn off automatically.”
This I can believe.
I hope the EM-6 finally emphasises function over form and a larger grip would be great too. This could be the perfect body for the 300mm f4.
Please no. The grip on the E-M1 is not too small.
“Some of the beta testers.. …after 15 minutes”. That would be a really dumb reason to not release 4K at all. I bet 99% of all the shots that would be taken with 4k would be way less than 2 minutes. Propably 90% less than 30 secs. If that really is the situation, we could hope to see a “leakage” of some sort, so that people could use it at their own risk.
Heat doesn’t just go away as soon as you stop recording. It slowly builds and slowly decreases. You could only shoot short bursts of video followed by cool down times. Not very useful for anything other than a novelty. Yeah, release an official firmware that might ruin users cameras that they could just use “at their own risk.” Sounds like a brilliant idea…
Em1 has heat sensor, so there is no real risk.
And by the way. There seems to be a pattern that the ones with professional photography background/connections (like you Vincent) are telling it is not coming. And the ones with the video background are telling the other story > Olympus is testing two firmwares with separate groups and giving true/false information as they see best.
Sorry for spamming, but notice also that one camp of sources is saying “no video improvements at all” and the other is saying “4k + new framerates”. If 4k is not coming, then why is no source telling “No 4k but yes to new framerates”, since the 25fps for example would not cause heat issues?
Not convinced… and admin, how can it be only FT4 if you’ve seen it with your own eyes? Still seems fishy. Also, where is the 24 fps? That should be included as well. Nope, if it was any company other than Olympus I’d be more convinced this is real.
Do you know what difference is between 23.976 and 25?
You can’t even see that difference.
you could check wikipedia(like most people do before coming up with smart replies)
Check EOSHD.com
still more interested in the stills department, but might be a reason to get reaaaaaallly fast sd cards
That would be amazing, putting Oly on the same level or above Fuji. Now, time to add a few features to E-M5, at least all what E-P5 with the same processor has (autopanning detect, focus peaking).
Does X-T1 record 4k?
No.
Video frame rate selection – In addition to the existing 60fps and 30fps selections, 50fps and 25fps, as well as a 24fps selection will become available to users. 50fps and 25fps allow video editing in the PAL region, such as Europe and elsewhere, without converting the frame rate. The 24fps will offer movie-like video capture and play back.

Thanks for URL. Interesting to know what rumored features are for that camera.
I am so uncertain about this. Few my thoughts:
1) Update goes from 1.4 -> 2.0 with only couple art filters, live composition from E-M10 and software keystoning, without any real improvements to EVF refresh rates with art filters or peeking. If trusting the “unofficial” firmware. So basically nothing that would not fit to 1.5 update.
2) So many saying 4k coming and then many saying it isn’t coming. Either there is just single individual claiming that 4k is coming only to tease us (finger pointing to that individual on twitter shooting skateboard parks) as trying to push Olympus it is coming because E-M1 has same sensor as GH4 (but different electronics and CPU) or then there is multiple testers that has had the firmware for test purposes. In software development there is simple thing called “branching”. Where each developer/engineer can work with different functions/features without affecting others. Question is just what features gets pushed to main branch for release. Do not think that everyone gets every feature and code everytime. Simple distributed development and testing.
3) Olympus pulled the firmware off their servers in few hours after it dropping there. Or was it there longer? Who found it? Who tested the filenames in their seek?
Olympus follows 43rumors twitter/site and of course reacts to it.
But if it is official firmware and in official directory, why doesn’t Olympus Viewer software inform users that there is a update? Was that the way someone found it? If so, why need a special third party tool to fake a update server to be able flash the firmware?
4) I have read that some say when using Olympus updater software, it says the firmware is 1.5 but after flashed to camera it say in camera it is 2.0. If that is true, it shows that it is not finalized firmware. A common thing yet that not all version numbers are changed correctly.
5) I would be interested to see these new photos. Some believe it is on test bench or prototype camera but isn’t that already clear it would cause Admin not to say he/she believes it is true? If I would see a photo from camera opened on typical engineer workstation, I wouldn’t even believe it is E-M1.
6) If the firmware exist and is on field testing (how many remebers the iPhone 4 leak, phone got left on the bar? You NEED to make testing on field, and what is better way than get some common video guys sign a NDA and test it? Or get Olympus own skilled workers (who are already under NDA) who are trustworthy to do some field testing on real scenes? It is more likely some people see the camera but who comes to look video settings on cameras what someone is filming at the moment? It would happen at scene or testers home or where the camera is kept safe.
7) If it is a prototype, you don’t want to make the camera look like it is a new model as it easily gets spotted and shared quickly. Instead you can design it to existing camera body, if it is technically possible. But at that moment the camera needs to be so far in development that electronics etc doesn’t anymore change, and if they don’t change, then body doesn’t need to be changed either. So if the body is E-M1, it is less likely a new model (unless Olympus release silver E-M1 and then E-M1n)
8) We are only four days (4) from photokina. Very likely there is currently still engineers working with the firmware. Polishing, testing and maybe even adding new tested features.
There can happen anything until the presentation starts. Just like with Microsoft and their “Surface Mini”. The device exist, it was manufactured couple thousand units but in two hours before presentation it was called that it will not be revealed and presented. Audience were already in the show room, reporters had been reporting preliminary happenings etc.
ANYTHING can happen until the moment the presentation is done.
9) Is the E-M1 SILVER MODEL really so much expected? E-M10 live composition and couple new art filters etc? They wanted to build whole new camera just for that? Almost a year after release? A silver model doesn’t take so much time at all! You simply don’t paint the magnesium body with black color, you order different colored/material knobs and dials and you call the day!
After one year, real sales booster would be improved video qualities. There is huge demand that there would come 25fps mode. Not 24fps or 60fps, just the 25fps.
10) It is silly that Olympus has their own pocket cameras like TG-2 that has variation of framerates! Example: “1080p, 720p, VGA, High Speed 120fps, High Speed 240fps”
http://www.getolympus.com/us/en/tg-2-ihs.html
Why…. oh why leave OM-D, their best DSLM line cameras (and same time PEN) without? Well, different engineers etc.
Why release E-PL7 before Photokina?
120 and 240 in movie menu …no way at 4k
I would not even dream on those!
But if the framerate is in movie menu, it means it is slow to change. Why not in the Shooting Menu 1 or 2? 1 Would be more logical for quick changes.
But probably it is that you could choose framerates for 4k, 1080p and 720p separated.
Or is the “Movie Menu” the “classic menu” what you get when Mode Dial is in video and you press OK?
If so, then it is easy to to get but if it is menu > gear > I menu, it is far too deep.
Since Olympus doesn’t have the additional heat-sink tech that Panasonic uses to cool the GH sensor (and can’t, because IBIS) I am thinking that the 4K capability — if it exists — will have to be heavily compromised: either very short recording time in 4K, or need to use an external recorder a la Sony A7s, or both. The E-Ms are hot-running cameras to begin with — ever notice how warm your E-M 5 gets around the grip area when shooting sequences? Sometimes when I take out the card, it’s uncomfortably hot to the touch.
So I’m guessing that Olympus’ indecision on whether or not to include 4K in the firmware update is primarily a marketing concern. Do they include this feature and risk being ridiculed for its lame implementation? Or do they leave it out and risk being dismissed as being behind the times?
“Since Olympus doesn’t have the additional heat-sink tech that Panasonic uses to cool the GH sensor (and can’t, because IBIS) I am thinking that the 4K capability — if it exists — will have to be heavily compromised: either very short recording time in 4K, or need to use an external recorder a la Sony A7s, or both. ”
You do know those two are illogical?
The sensor doesn’t cause such heat, CPU and Battery does. That’s why external recorder is expensive if they have own CPU for the task to easy the heat problem in body.
Olympus hinted about new external attachments (AFAIK) what could be a such thing.
And ever noticed how it is the battery and CPU that heats up? Check my post below about GoPro temperatures in small, weather/shock proof plastic cases with URL’s to videos and reviews about heat with 1080p 30/60fps.
That’s my thought exactly. The heat after a “heavy” session in burst mode is quite impressive. I guess we’ll have just to wait for some days.
What is “heavy session in burst mode” in this case?
4/5 shots to someone walking in front of you, then wait 10 seconds for another person and shoot 4/5/6 shots. Repeat this for 20, 30 minutes and you’ll notice the camera is hot.
I notice this problem with any USB stick I pop in my Mac and then copy a few GB of data to. It gets warm.
True, but we’re talking about cameras, with different components compared to a USB stick. How much does the sensor “suffer” from heat? Can the heat damage some inner parts?
The components are not that dissimilar. Both the USB stick and the SD card are writing to flash memory chips so get hot if doing so for a long period of time.
I don’t believe you can damage the internals of an E-M1 because the manual says that it has inbuilt thermal protection and will shut itself down. It will display a warning indicator in the display if it gets too hot.
“If the camera is used for extended periods, the temperature of the image pickup device
will rise and noise and colored fog may appear in images. Turn off the camera for a short
time. Noise and colored fog may also appear in images recorded at high ISO sensitivity
settings. If the temperature rises further, the camera will turn off automatically.”
That’s good to hear, but still I see heat as an issue. I have never reached the limit and had to turn off the camera, but I don’t like the idea of “melting” the sensor 🙂
I’m not interested in video, I would be pleasantly surprised to see this feature on Em1, but only because it’s already a great still camera and this would make it even more attractive.
Then, if it will record only 15 seconds before reaching the heat limit, I don’t know. It would look like a joke..
Marco, you are right: heat is bad for everything non-metal. Back at university, we ran tests on pieces of different plastic. Every 10 degrees (Celsius for the non-metric folks), you can expect lifetime to be cut in half. However, even if you shoot a lot, your camera will be cool 80% of the 24 hours we have in a day. So don’t worry too much.
Of course, a larger camera can have better heat sink, but that is not up your alley I understand. When are you going to move to Canon or Nikon?
🙂 I’ll consider Canon and Nikon when they’ll release a promising mirrorless system, with a great lenses roadmap, if it means a new mount.
The only word that comes to my mind is “never”.
To me it looks that Canon or Nikon can never release a mirrorless small format camera or even APS as they are locked to their objective markets.
So they can only remove the mirror, add a EVF and call the day. But would their customers find it good? Mirrorless large and heavy body? Many would not care at all. Especially if they could get faster global shutters electronically etc.
With the existing mount their cameras will always be big. I hear more and more people (read pro photog) loving their DSLRs IQ but complaining about the weight of the camera+lens combo.
It’s not that people are weak, it’s simply obvious that at the end of the day a mirrorless user is less tired, after a whole day shooting.
Sony a7r delivers great IQ, it’s “full frame” as it must be to be considered a pro camera (sigh) and it’s, along with Fuji, the first approach to this world. Often just as a back up camera.
I was the only one using the “toy” sensor m43 system, but files delivered surprised many of the old photographers.
Sure, but the problem is sensor size. No help to make body small like Sony with A7 series when we objectives will always be huge.
Olympus designed 4/3 that in a mind. They knew by experience what are the most common shooting settings among professionals and found that very rarely they could use apertures below f/5.6 when using small format. Then they found that they could rarely use f/5.6-7 because it objectives drawed unsharply too often before that.
So Olympus sit down with Kodak at same table and drafted a sensor size that optically is easy to fill and that technically is easy to manufacture with enough pixels.
The result is that objectives are tack sharp at wide open, apertures like f/1.8-2.8 gives more than enough depth of field control and same time camera and objectives can be made smaller.
But it was not until Olympus and Panasonic designed a m4/3 mount to remove mirror as life view was possible with better tech now. And then Olympus/Kodak design got finished about smaller body.
Sony did nothing amazing with A7 size. Olympus was there already at 1972. The problem never was to get body small, it is to get it objectives size and weight down while quality up.
But for many pro the bodies like 1D or D4 are the “masterpieces” as you need to carry to huge monsters with integrated grips so you look cool and you have lots of physical buttons and switches to adjust settings.
But still (IMHO) nothing compares to the body what E-M1 has. It fits to hand and has controls like no other camera has. It is direct continue to my mind, what no Canon/Nikon any model (used all of them) ever have managed to get.
But many still would want Canon/Nikon take their current bodies and simply remove the mirror. That is their only change now. Make a couple models where body is small or huge and keep same objectives.
Or make totally new objectives and finally come to m4/3 world.
If I would be their board chairman, I would say they need to swallow their pride and take m4/3 system. Sure it would generate shock to many but their brands would allow them to fight a serious market position. They have knowledge to improve sensors or offer something new thinking (or Sony has).
I agree. Leaving aside the a7 controls, that I don’t like, its main problem is the size of lenses, if you want bright ones. This is not only because of the sensor size, but depends also on the mount, the distance flange.
Leica M system has 35mm sensor but its mount allows small and compact lenses. Manual focus, but compare them to the Otus lenses and the latters look like a joke.
Back to big N and C, as you said they should swallow their pride and jump into a serious competition. Times when only a bulky DSLR could take a good photo are over and many people, from amateur (some of them will be tomorrow Pro photographers) to elders are opening their eyes.
TOP 5 REASONS WHY CAMERAS HEAT UP WHEN BEING USED FOR 30 MINUTES:
1: The users hands are too hot.
2: Too much direct sunlight. Cameras should be shaded at all times. (especially the black ones)
3: The engineers who design today’s digital cameras screwed up by not installing liquid cooling systems. (big dummies)
4: Most of the world’s photographers live on or near the equator.
5: They are supposed to! They contain silicone chips, diodes, capacitors,
resistors, circuit boards, and powerful batteries. (i.e. electronics “heat up”
Point 3 is very true, I wonder when someone will implement that.
No heat here at all.
That’s why there are first-tier manufacturers. But I know you are too “smart” to buy a Canon or a Nikon system…
In ten days at the Venice Film Festival I witnessed a “collegue” running to the Nikon service because of a locked mirror on its d800, another one renting a new 70-200mm because he hit a chair with it and it had an issue with the focused area, and a Canon user going nuts because the card got erased without reason and lost a full day session of photocalls. They were just three out of 50, but still I have never experienced any issue.
It’s not about being smart, it’s about knowing and mastering some gear.
That’s why. 😉
A friend of mine was in Calcutta in a bro_thel, they had a red carpet and there were some smashed E-M1 bodies lying about. They had been put there to arouse software people they say.
…and in addition to posting the occasional uninformed comment, you are also a camera engineer …F A I L
The heat is there for a purpose. With a freeze proof camera it’s expected you’ll be taking pictures in a freezer. The heat keeps your fingers working.
Maybe 4K will be only on the new, “silver” M1?
What a nice gift for the 9/11 feast! Thank you!
Lmao 4K is not coming to the E-M1. LEAST of all at fricken 240fps! Need some great drugs to believe that.
No one said that there will be 4k at 240fps.
LOL, 4K at 240 fps, good one! No admin clearly stated that he saw 4K UHD resolution in the firmware at 24, 25 and 30 frames per second.
WE will all laugh our ass off at pseudo camera engineers like you when the EM1 is 4k capable. You and your kind couldn’t even unscrew a toilet seat…what would you know about what’s in a 2014 digital camera body? FAIL!!!
This thread is getting hotter than a E-M1 shooting 4K 15 minutes straight…
“Facepalm” LOL. A very good move from Olympus, competition is welcome in 4K territory.
Where have you been educated “eno”?
What a comment… LOL. On the “school of life” men, where else? :).
I’m curios why capturing 4K from the sensor would generate too much heat on the sensor and would need a special heatsink, but a 30 minute long exposure does not. Anybody can explain that to me ?
I’m not talking about heat from battery, CPU or SDCard, just the sensor.
At a very fundamental level every time you take a 1 and turn it into a zero that energy needs to go somewhere. Then you have to move the data from the sensor into the memory, resistance in conductors is fairly low but not zero. The more data you move, the more energy you use. 4k moves a huge amount of data. Do the multiplication 11fps at the normal 16mp with 8b per channel raw data and then do the same thing with 4k at 24 or 32 or whatever 4k is. The power scaling and thus the heat will be approximately proportional.
The original question was from a sensor point of view only: “I’m not talking about heat from battery, CPU or SDCard, just the sensor.”
Sure, encoding needs CPU power, draws energy and dissipate heat… But as a matter of fact, the sensor outputs its “full frame” data to the EVF/LCD in “real time”, and it’s hard to believe that 4K, HD, dunnowot encoding would have an effect on the sensor (unless the sensor does some kind of specific pre-encoding for video?).
Normally the sensor should not get hotter if outputs 4K, FHD or simple live view. The difference in heat for 4K video recording comes from the processor, motherboard, card writer and battery. At least this is my understanding of things.
Yep. Sensor isn’t a problem.
Admin, you should ask this source when we will get the Firmware update that converts the EM-1’s DR, tonal range and ISO performance into a D4. It has about as much of a chance as this 4K rumor.
4K is very possible as at least sensor does support it to 30fps. Question is about rest of electronics that we don’t know anything about!
Ah, yeah … no. The D4 has 2 more stops of DR than the E-M1. Sorry.
Jpeg… Not RAW…
Yes, RAW.
You guys are killing me with these rumors
When EM1 was released, we complained it had poor video and, all thoes people who said it would take more than FW for even 24/25/30 switchable… lol
Now FW is doing 4k and 240fps – knew it!
mfw
I would die for laughs if it would be a 4k with such frame rates and bitrate at current 24Mbits.
He who laughs in the end, laughs louder…
Olympus can’t even manage a decently sharp FHD image, let alone 4K.
Plus, their codec sucks like airplane toilets, how could it ever hold 4K???
Put your reality hats on people!
If true that would be awesome!
Rubbish. Click bait.
4k? I don`t know… but 120 & 240 fps is GOOOOOOD!!!
Stop being so gullible admin. I bet you my entire stamp collection that this is not going to happen.
Dear friends, today is the great feast of 911. Let’s all celebrate and throw away those awful cameras that keep you from doing what you really love. Like annoying the americans,
So why not the EP5 as well? Same dang thing. Come on…don’t leave us out man.
