GX7 test at DxOmark and CameraLabs

DxOmark (Click here) posted the full GX7 sensor test. And the big question is…will it beat the E-M5 sensor? The answer is…it’s pretty much on par (70 point vs E-m5 71 points). This is DxO’s conclusion:

The Panasonic Lumix GX7 is certainly a compelling model. Not only does it now feature in-body stabilization (that’s compatible with any lens fitted) but it also silences critics of the original GX1 over the lack of an EVF. Couple that with the competitive performance of the new 16-Mpix L-MOS sensor and you have a camera that’s classy, refined and very capable.

But you know, DxO has his own rules for judging the sensor quality. You don’t have to take them as a given absolute truth 🙂

So you may watch over at our friend Gordon from CameraLabs (Click here). He also posted a full GX7 test:

I certainly can’t say (as others have) that this is the best mirrorless camera, the best Micro Four Thirds camera or even the best Lumix G camera. There’s both pros and cons here so it really boils down to which features are a priority for you personally. It could be the aspects that annoyed me may be non-issues for you in which case it’s a great choice.

The greatest GX7 news of the week is that finally our US readers can get it in Black too at BHphoto (Click here). About time!

  1. now, already noone takes it seriously,I prefer to test sensors my self with some better RAW analyzer than the DXO.
    there are many better methods than theirs.

    1. the best method is the I will test mine and make mine the best in every sub FF formum in the world there is someone bleating about DXO.

      The overall score is pointless the DXO data is a very different matter ,if you take the trouble to look at that,you will get a very good correlation between their results and the real life differences between cameras.

      Honestly,the difference between the latest mFT { E-M1/gx7 } sensors and the other 16mp models from the E-M5 onwards E-M5/E-PL5/GH3 etc is pretty much zilch

      I see admin is in the fanboy true believers gang

    2. I have seen enough test results, scores and opinions from people who have used these cameras. In short the IQ of all the top M43 cameras are about the same. AF in these cameras is also quite similar. So, these other things are now the important deciding factors:

      – EVF (VF-4 and the EVF in E-M1 are better)
      – Image Stabilization (5-axis IBIS better for video and legacy lenses, and also better for M43 lenses like the 20mm, the 60mm, 75mm…
      – Lenses available, which is the same for all M43 cameras, except that the E-M1 can also use FT lenses.

      The only thing going for Panasonic camera seems to be video quality, price, and particular body features (fully articulated LCD, rangefinder style, body shape etc). None of those considerations have anything to do with still photo quality.

      Seems that Olympus is leading, which has been the case since the OM-D line was released.

  2. LOVE my E-P5…
    ….not that what DxO has to say about it makes any difference….they are useless.
    Of course my E-P5 and VF4 kicks the GX7’s butt in so many ways …this I already know! 🙂
    (bring it on Pantoids!).

    1. well,..i played with Gx7 yesterday at B&H while brought along my E-P5 too,.but ,damn The VF4 on E-P5 its sure make a lots difference,and.even though i have my E-M5 but i rarely shot with it just because of the quality viewfinder .the built in EVF on GX7 is very good indeed,.but …..is not like VF4 ,..just like what you see is what you get in term of exposure metering,.when i use my Nikon with OVF i have to guess what the exposure would be like, but with this VF4 i don’t need to guess how the exposure would be like

      not mention the JPEG quality of E-p5 even better than E-M5

      1. There are also color-correction problems with the GX7 VF especially in low light…it does not match the rear LCD or what comes out of the camera.

      2. The sensors tech has reached its limit currently. The difference between sensors is so insignificant that choosing any camera will result with almost identical picture if you process raw file. Choices between cameras now down to preferences to the camera body, ergonomic, weather-shield, EVF, IBIS, in-build flash and what not. Stop gunning down any camera that has a different brand that yours, just because you want to justify what you buy is the best.

        1. Panasonic has issues with the color rendering with it VFs….the GH3 is notoriously inaccurate compared to the files and the GX7 has been cited in many reviews as having fluctuating color rendering inconsistencies as well.
          Say what you will.

  3. -Like I trust Republicans are for ObamaCare… Very good cameras get the Slightest reduction in points, compared to their favorite (or hands-moistened with cash) cameras..

    Nikon and Olympus ALWAYS get a pass.

    Panasonic is the Underdog in the Camera Industry, but I’m cool with that. DXO will Never put a Panasonic camera over a Olympus one. Don’t even bother clicking the link and giving them a hit.

    1. Why don’t you geniuses download the RAW files from the GX7 E-M1 e-m5 et al and take a long hard look at them in a RAW convertor.The differences are microscopic. Olympus fanboys are like cockroaches ,unwelcome wherever the appear ,crap all over everything and it is easier to move out than try and get rid of them.

      If I was you guys I would be more worried about the impact FF mirrorless will have.Sure there are hardly any lenses and some of them cost a fortune.But,slap on your favorite FF from whatever brand you want focus with the excellent focus peaking and you have image quality mFT can only dream of.
      see,ya suckers

      1. …but if you hole E-P5 in your hand it is a nice solid camera, from a camera manufacturer, with great, color-correct viewfinder…oh…how…LOVELY!!!!!

      2. The only thing is DNA, focus peaking is not as precise as using a 14x magnifier view with the built in I.S. Also the cameras performance with manual lenses is unknown. Remember this camera uses a sensor made for these cameras and to avoid issues on corners because of the very short flange distance. It is designed to perform at it’s best with the new lenses which are designed for the sensors. So performance on the edges could be poor with older lenses. Don’t expect them to be as good as being used on a standard sensor.

      3. The more years I spend in this business, the more I’m starting to think that all this sensor size talk is nonsense. There used to be a huge difference, but now that the circuitry got so microscopic I think it’s all just a trick to fool customers.

        Why?

        If you compare MFT to ASP-C to FF, you have to compare with complete equivalence. And it seems to me, no matter what system, the lens sizes will be the same, the image noise will be the same, etc…

        The logic is that if you take a lens, the amount of light passing through the lens is the same regardless what sensor you put behind it. Picture a cone of light behind the focal point of the lens projecting to the sensor. Whether you put a FF sensor behind it, or an MFT sensor twice as close, it will capture the exact same light.

        The reality is that if you take an MFT camera set to 25mm f/1.4 ISO 200, or an APS-C camera set to 35mm f/1.8 ISO 400, or a FF camera set to 50mm f/2.8 ISO 800… everything will be the same. Exposure, DOF, noise levels, sharpness, lens size, etc.. everything identical.

        With f/0.95 lenses being made for MFT, and tiny mirrorless bodies with small f/2.8 primes being made for FF, the difference is even further diluted. Except that with FF you get to fool people with great high ISO noise (because ISO is not reported in equivalences), and with MFT you get to fool people with aperture numbers on the lenses (because aperture is not reported in equivalences).

        Meh.

        1. To continue on this, I’ve reached this conclusion after having used a Nikon D7000, Canon 6D and Olympus E-P5 side-by-side for a few months now. Every day I am astounded at how similar the IQ is between these cameras. It is funny how people go yapping about how A is better than B when the differences are so ridiculous.

          And then it comes down to the practicality of the cameras. And there I think the GX7 and E-P5 are absolute winners and some of the best cameras on the market right now.

        2. Mike, when you try to take the same picture with 2 different media sizes (sensor sizes if you prefer) you indeed end up with ‘full equivalence’, and as long as that doesn’t make you end up with iso or aperture going out of range for one of the systems, you should end up with pretty much the same result (not 100% exact, but typically so close that differences don’t have any practical meaning). Technically, lenses for the system with the smaller medium can still be smaller, even when using the exact same absolute aperture. The simple reason is that while focal length isn’t the same as length of the lens as such, there is a strong relation between the 2, and making a 50/2.8 that is exactly the same size as a 25/1.4, not just in diameter, but also in length, cannot be done without making more severe optical compromises (given that the 25/1.4 isn’t needlessly large).

          Having said that, I believe this to be a popular but rather misguided approach. Cameras aren’t the same, handling isn’t the same, features aren’t the same, and in all likelyhood, you wouldn’t be trying to take the exact same pictures in many practical situations, and one should in my opinion look at how to best exploit a camera for a given set of situations, and then look which system gets you the best results. That isn’t just about image quality, but also about things like how much a camera (or you as a photographer) interacts with a scene, positions that would be easily achieved with one camera but less easy with another (size, weight, DOF control etc).

          Trying to eliminate all differences is in my opinion the wrong way for figuring out what best matches your needs.

          (and in general agreeing with what you said).

    2. Panasonic is the Underdog in the Camera Industry, but I’m cool with that. DXO will Never put a Panasonic camera over a Olympus one. Don’t even bother clicking the link and giving them a hit.

      Until Olympus used a Sony sensor in the E-M5 Panasonic had the best mFT { GH2,GH1 } and yes DXO tests showed this

        1. Oly do possibly have a better electronics fedility supproting the sensor than panasonic…

          The EPL1 gave possibly the best result ever seen from that 12Mpix sensor – prefured the output over the EP3!

          Oly have histroicly been the lowest of dogs when it comes to sensors….

  4. Yawn, GX7, old news, Admin!! We want more GM porn pics!!!! 😉 (Please nail the video Panasonic, please nail the video…)

    Keep up the great work.

  5. Panasonic is finally catching up to Olympus in terms of image quality.
    The GX7 seems to be better in IQ in the higher ISO ranges than the EM5.

    Exciting times for the M43 world.
    Lets hope that DxO will do the same tests for the EM1.

      1. Stop talking when you’ve never held a camera. He’s talking about real world results, not abstract and useless “points”

      2. Check out the DR results. The GX7 beats the EM5 in the high ISO areas.
        And this is the area, where Panasonic was lagging.

  6. It’s truly absurd how many reviewers compare the GX7 to the EM1 without mentioning what a freaking obese behemoth the latter is. Unbelievable. You’d think none of their readers got into m43 for the size…

      1. Nice call….it is only the grip on the M1 that increases the depth…but hell the eyepiece on the GX7 sticks out so far they are just about EVEN!!!!!! LMAOFOTF!

    1. right…plus the almost 1″ (that is an enormous difference) of extra *height* courtesy of the famous “hump.” Also, is there some compelling reason thickness doesn’t “count” if it comes from the grip? After all the grip is where the larger battery is held that the reviewers also can’t stop comparing to the GX7’s “inadequate” battery. It’s bigger. There’s no way to tell me 1″ taller is not “significant.”

      1. Freaking obese behemoth? What a joke. Yes, the E-M1 is bigger. But it is still a small camera. Yes, the GX7 is smaller. Go buy it. To me, the GX7 is a nice camera. But it is too little increment over my E-M5 to consider it. Maybe the E-M1 also is too little improvement over the E-M5…

        The E-M1 is smaller than the E-M5 with landscape grip. And lighter.

        Battery capacity of the GX7 a soare point?? One thing for sure: the extended grip on the E-M1 compared to the E-M5 does *not* contain a battery. Unfortunately. To me, the E-M1 would have been more of a pro camera if it had a new, larger, higher capacity battery.
        —
        In summary: m43 is lucky to have as nice cameras as the E-M1, E-M5, E-P5, GH3, GM1, and GX7 (in alphabetical order). And loads of lenses.

  7. Yeah, I’m happy with the G6, still and think it is the camera of the year, as far as I’m concerned – flat black, manual movie, great sensor, silent shutter, NFC and all in a slim, unpretentious body.

    I think most people would have a hard time seeing any difference in the current crop of 16mp M4/3 sensors, in real world shooting. Of coarse there seems to be a lot of people that are not interested in real world shooting, but prefer to buy what is rumored as the best and spend their time on the web reading test reports and trying to convince everyone else that their money was well spent on the very best, according DXORockwell etc.

    You would think that they were camera breeders or something, searching for that Olympus with the pedigree so they can breed it with their old EM1 and make baby EP6’s that they can sell and gloat over.

    To me cameras are just tools to make images and movies it’s nice if it comes together in a complete package, that is also comfortable to hold.

    The GX7 is now available in black, how nice, it’s too bad that the VF sticks out nearly twice as far as that of my G6, or I might have been interested.

        1. According to Terada they are all designed for girlies, anyway enough of this I am off to play with my dolls xox lol

  8. I haven’t still had a chance to use GX7 and especially the EVF, but I guess that despite it was a good decision to incorporate EVF in the body, in the way the decision was executed, it doesn’t count for much, because the EVF should have been bigger and better. And many will also look to other cameras for IBIS for video, mic-input and weather sealing. Still though, it’s a very capable hybrid stills/video camera and the concept, ergonomics (except EVF) and design are right.

  9. In other words, (almost) on par with GH3. And this will be true of GM1, too. I think it is good that Panasonic is using the same “top sensor for everyone” approach that Olympus started using.

    So, the only remaining question is if the E-M1 shows any improvement (which will possibly presage if the Sony a7 shows any IQ improvement over the a99 and D800).

    And what the trolls will say if it does not.

  10. Sjee what an fuss about DXO. DXO is a good source for comparing. One thing is clear…….also the newest M43 sensor can not touch APSC and FF. For example a NEX6 which costs 500 euro scores 78. the GX7 and EM1 never gonna touch that. A pitty DXO does not rank the Fuji X-E1 which costs 700 euro. it will be of the charts. Also funny….A very very old Nikon d90 scores 73. Thats still more than the best and newest M43. M43 is nice but please stop comparing it with APSC and FF.

    1. “please stop comparing it with APSC and FF.”

      That is funny for you to say after having spent a lot of words on doing just that.
      How about you take some of your own medicine?

    2. Ololol, and we all know that you cant take pictures without a camera that has a score below 73 ^^
      troll yourself…

    3. I agree that a 24mp Sony APS-C has better resolution than a 16mp MFT. BUT, BUT, the current APS-C lenses (not FF lenses mounted on APS-C) are half that way in terms of resolution. So about only half of those 24 mp are resolved.

      However, there are MFT lenses like de 75mm that can resolve 13mp from a 16mp sensor resulting better sharpness and iq (at lower ISO)

      1. “not FF lenses mounted on APS-C”

        Its damn lucky that there are hundreds of “FF” lenses then isn’t it lol Here is an example comparing a couple of longer portrait lenses the 75mm on the E-M5 resolves 13mp weighs 305g costs £719 , isn’t weather sealed , and doesn’t even come with a hood. The 85mm on the D7100 resolves 15mp , weighs 350g costs £369 , is weather sealed and does come with a hood.Not forgetting that F1.8 on Nikon DX gives the same DOF control as F1.2 on mFT

        They both have almost identical, Transmission, Distortion, Vignetting, and Chr. Aberration. Now despite the lack of weather sealing the 75mm is a well built and attractive bit of kit . Nikon DX shooters have lenses covering { FF equiv} from 14mm-1800mm with literally hundreds of choices of native mount AF lens on and off brand.

        http://www.dxomark.com/Lenses/Compare-Camera-Lenses/Compare-lenses/%28lens1%29/898/%28lens2%29/823/%28brand1%29/Olympus/%28camera1%29/793/%28brand2%29/Nikkor/%28camera2%29/865

        1. I use the 75mm on Olympus as well as the Nikon 85mm on a Nikon D7000.

          If you think that the 85mm resolves the same as the 75mm, you have obviously not used any of these lenses.

        2. I am a NIkon DX user. Below 17mm there is nothing from Nikon faster than a f/4 zoom. The choice in lenses in the 10-35mm range is appalling. Nikon has nothing where MFT has 12, 14, 17 and 20mm primes.

          The Panasonic 25mm is lightyears better than the Nikon 35mm. The bokeh of the Nikon 35mm and 50mm is so crappy, I’d take the cheap Olympus 45mm any day.

        3. And yet the Nikon photographers I work with are rather jealous of the glass I not only own, but can easily carry around all the time. Gotta wonder why.

    4. “the newest M43 sensor can not touch APSC”

      Such a false generalization.

      How about the cheapest Olympus vs the newest APS-C from Canon:

      EPM2 – Overall Score: 72; Portrait (Color Depth): 22.7 bits; Landscape (Dynamic Range): 12.2 Evs; Sports (Low-Light ISO): 932 ISO
      70D – Overall Score: 68; Portrait (Color Depth): 22.5 bits; Landscape (Dynamic Range): 11.6 Evs; Sports (Low-Light ISO): 926 ISO

      Yup, better.

      How about with lenses:

      E-M5 + 45/1.8 – Overall Score: 23
      5DMKIII + 85/1.8 – Overall Score: 26

      Not as good, but the FF combo costs $3460 vs $1300 (then there’s the bulk/weight) for 3 pts differential in this case?

      1. dxo also doesnt count software correction, so m43 lenses always will look worse than they actually are. Software correction is part of lens design for m43, so removing it will just cripple the results.

      2. There are the nerdy kids who look at the numbers and the ubernerdy kids who analyse them.
        Of course, those numbers have no bearing in real life, but nerds haven’t got a life, this is why DXO hasn’t shut down yet.

        1. I’m merely replying to Viezevure. Other than that, I could care less what DxO says though it took literally a couple minutes too look up those numbers. To me anyway, if the print looks good, the camera/lens is good.

  11. A camera is obviously more to it than its sensor.
    Lens selection, AF speed and accuracy, body size, handling, accessories, price and other costs of owning the system.

    In many of the above criteria, m4/3 is doing very well. (I am saying this as a Sony NEX-7 user)

    Having said this, I do believe that there could a worrying trend that m4/3 sensor are not making enough leaps in IQ.
    Many do not like DxO but I use it just to have a numerical understanding & quality of the sensor (NOT the camera).

    http://www.dxomark.com/Cameras/Compare-Camera-Sensors/Compare-cameras-side-by-side/(appareil1)/901|0/(brand)/Panasonic/(appareil2)/896|0/(brand2)/Sony/(appareil3)/736|0/(brand3)/Sony

    Total Score : GX7 = 70 ; RX100 II = 67 and NEX-7 = 81
    The difference between Sony 1 inch sensor and GX7 is 3 points while GX7 and NEX-7 is 11 (NEX-7 is now 2 years old)

    Is there a risk that smaller sensors camera will catch up to m4/3 in the near future and does that change the value proposition of the system?

    The second issue is that price and other costs of owning the system has gone up dramatically for m4/3 since my GF1.
    New lenses and camera bodies are more expensive than ever. At the same time the price for traditional DSLR have tanked.
    If this continues, will the m4/3s system price it self out of its future?

    1. Yes, this is certainly a danger.

      A big price crunch is looming in the mirrorless world. Panasonic, Olympus and Fujifilm have enjoyed very lucrative margins to date, but Sony is putting the pressure on now.

      Lower prices is good news for enthusiasts, but it may mean the death of one or more of our favorite camera systems.

    1. Yeah, with how much the d800 14-24 weights, it will no doubt crush those tiny cameras and lenses. It’s like elephant will step on a fly 🙂

    2. Which I suppose is why I’m doing most of the corporate event photography for the company I work for nowadays with a twin E-M5 setup, instead of my D700 and now D800e toting colleagues who used to do that until just over a year ago.

      And why I let them do the big landscapes and such that we need at times.

      Different devices with different things at which they excel.

  12. This site is a troll feast. 90% of comments are complains and “mine is better than yours”. Useless. As my comment, because admin is not going to do something to solve this situation. 100% limit of useless comments is not that far.

    1. mmmm its an intresting mind spew sometimes… and just now and again somone talks about cameras… occationaly m43 ones too!

    2. Seriously, trolling really got unbearable. Apsc and 35mm (and not ff, u useless trolls) are wayyyyyy better than m43 (which is going to sink, die blah blah blah) and ur bigger sensors cameras are definitely the best.
      Now leave us in peace with our sucky m43 gear and go to really buy a camera and start to learn how to take pictures, suckers

  13. no surprise there. most sensors these days are pretty darn good, especially since most people don’t even have the screens to show such wide gamut, nevermind print it!

    the race now I think is for EVFs that make sense and don’t lag. Olympus has a really good shot here of coming out with a fantastic looking PEN if they look to their heritage. the vf4 may be awesome but it’s ugly as sin. if “rangefinder” is your style, doubt you can get better bang for your buck than the gx7.

  14. Ha ha Mister craps should be so angry. After all the “steve Huff is a moron” for saying the truth, can’t wait for all the DXO hate.

  15. Wish Panasonic would stop d*cking around with they toy introductions. While Sony and Friends(tm) are playing for keeps, Panasonic is living in it’s own world of make believe.

    Where is my GH5 with 4K video Panaman? Put up or go home.

    Sony is about to get all up in Pany’s behind with tomorrow’s introduction of FULL FRAME mirrorless nirvana and still, Pany is giving us Hello Kitty(tm) toys.

    So sad.

    1. Check out the graphs, Oly fanboy.

      But either way, it is good to have choices. Some people prefer the GX7, and others the EM5/EM1.
      What good is the EM1, if YOU can’t take decent photos?

  16. I read the review since last night .
    This is not good , even is close but it’s still consider behind the race .
    The Pana guy in the workshop told me GX7 sure beat EP5 & EM5 in IQ , 3 days before GX7 available for purchase .
    This is disappointing , I need to take action against this Panasonic guy .

    1. depends what iq is for you, gx7 has better at higher iso, has better resolution due to removed AA filter. Compare raw photos on dpreview page. You will see, than gx7 is slightly more sharper and has better resolution. But still, for me vf4 is far better than gx7 tunnel vision vf. + gx7 only goes up to 2min in bulb. You can forget night photography with gx7

      1. thats not true – images from the GX7 look softer than from its 16MP MFT competitors. at least according to DXO the GX7 has less resolution, see lens comparison.

  17. Admin, can you get ride of these horrible floating ads that have recently appeared on the site? They are horrifically annoying, and hinder the ability to read the site…they jump all over the place when scrolling, especially on a mobile device. They’re intrusive enough that it seriously reduces the enjoyment of visiting your site.

  18. No surprise here, pana is BEHIND. Pana can’t even touch the “old” EM5. So after the useless tiltable EVF, the CHEAP plastics feels, the ridiculous 2 axis IBIS, the poor jpeg engine we can enjoy now the already outdated sensor! Let’s face it, to buy a lumix over a olympus you have to be a hardcore fanboy like guilio sicocorio or a absolute idiot! nuff said

  19. He-he, the EPM2 blows all three out of the water. EPM2 ISO: 932!!! LOL!!! Going to buy another epm2. Maybe today. Was hoping on EP5 and GX7. Disappointed. And enthused about a second EPM2. The correct decision. And let’s see the EM1 ISO. I can predict it. Three times more expensive and …. But let’s wait.

    1. I rather go use it to take pictures. I know you aren’t interested in that but in compensating for your small ****, but those of us who are interested in pictures generally don’t buy cameras for reselling them (its generally bad business as well, but alas, if you want to throw away your money like that, be our guest)

  20. GX7 high ISO result is realistic. In DPreview comparison, GX7 seems a bit behind latest Olys, no big surprise there. Pity they haven’t put GH3 sensor in there.

    Better grip + EVF or better IBIS + better high ISO, that’s the dilemma…
