43rumors reader Gov sent me this:
“Gh4 will get post focus too, only later. This was said by a representative at fotomassan in Sweden. The clip is here (video on top). As a Dutch guy I can understand most of what he says and he says it at 11:35.”
This is how Panasonic described how Post Focus works:
Post Focus will enable users to select an “in-focus” area after shooting with a simple interface. This function has been developed as a further evolution of 4K Photo technology to prevent out-of-focus errors and offer additional creative freedom.
By combining high-speed, high-precision DFD (Depth From Defocus) auto focus technology and the 4K Photo burst images in 4K resolution are shot at 30 fps while shifting the lens to set focus on approx.50 areas (*TBC).
With the Post Focus function, the best image can be selected from the 4K burst images shot with different focus areas. Once the composition is fixed, you are free from the job of serious focusing. In addition, this function can be used for creative photography such as landscapes or portraits. Users can pull different impressions out of one picture by changing the subject to enhance it with focus. The operation of the Post Focus function is quite easy – just touch the point where you want to set focus while playing back the image, no matter where the original focus area is, and the image with different in-focus area will be produced as a separate photo.
Panasonic will introduce this Post Focus function via a firmware update for LUMIX GX8, LUMIX FZ300 and some other models in late 2015 and 2016 will study to integrate it into upcoming LUMIX digital cameras as well.

ist possible?
Of course!
What this just does, is that you hit “4K Photo” mode but this time more like “4K post-focus” mode. Camera will take those 50 frames with 30fps speed (so 1.6 seconds time) in 8Mpix resolution (it is 4K video!) by moving focus quickly from close to far.
And just like with “4K Photo” mode where you can choose the frame that has the moment, you can just tap the screen the position that should be in focus and the camera will choose the corresponding frame that has it in focus.
Then when you have selected the frame, you need to extract it from the video as separate JPEG file.
The quality will be lower like in “4K Photo” mode, but you have 8Mpix image that has like JPEG compression of 60-70/100.
It is better than not having anything in focus at all!
For others it is just easier to take the shot correctly in the first place.
And this will not replace lightfield camera as this takes 50 frames worth of time (30fps speed) and things moves while doing so.
50fps on post-select shooting file with 30fps on 4K photo is impossible.
frame will shift or rolling if take photo by hand.
1.6sec was too long time that I.S. can’t manage stable image.
for more i want more detail about post-focus function
Yes, I can confirm that it is indeed what he says. Timeline for the firmware release is “later in the spring”. For the FZ300, G7 and GX8 the corresponding firmware will be released in “about one month” (from the time of the interview, I assume).
Tried posting this in the comments for the 100-400 “Panaleica”, where the video first appeared, then again in the “(FT3) Panasonic Firmware Update for FZ300, G7, GX8 coming soon?” and as a separate rumor but I’m glad it finally got through 🙂
I guess you pointed me to it in that thread, so I took a look and was happily surprised when I heard him say that, so I send a message to the 43rumors. I have a GH4 so will be interested in how it works in reallife.
Good, just wanted the information to get through. Usually I’m not able to contribute to these kinds of sites so had to try when I had the opportunity. If the video would have been in Dutch I would have been out of luck 😉
COuld be. I never had a lesson in Swedish and can understand most of it when I concetrate, reading is quite easy as are the other two Scandinavian languages.
A pretty brilliant idea for solving missed focus problems without adding cost!
The cost is that you only have 4k resolution. I’d prefer Panasonic improving the AF in general.
Are you limited to picking one picture, or could you use all 50 in Helicon Focus or Zyrene to do some image stacking?
In-camera stacking, as in the new Olympus Firmware update, might be more useful.
focus stacking will release next firmware on Lumix camera.
see on Photorumors.com.
Any source post about (only) post focus.
but Pany give more option.
improve continue af on GX8/G7.
Hdmi connection,recordable to external on G7.
So many shaved heads!
MPB is hitting lot’s of men lately , at a much younger age too! I know coz I am on my way there lol 🙁 And generally the next best thing is to grow a beard, so there you have it .
A beard, perfect.
Then you can do a brush up to combine it with a comb-over and look even weirder than Donald Trump! ?
Yeah, but like bike racers, where do they stop shaving after finishing their noggins?
it’s called Magic Focus app in the LG G3 smartphone.
Yay, you can now get mobile phone quality photos that are in focus.
Yes, with a mobile phone. Pan 4K stills are much better quality than phone stills, especially in low light.
Sounds gimmicky to me.
But, hey, what do I know. ?
Sounds downright lame to me
Hey, I was trying to be nice. ?
File it with the “art” filters. Use it once and never again. i.e.: Junk.
It would be nice if Panasonic would add some of the functions Olympus has, like focus stacking and the long exposure thingie instead of stuff like this.
Heh,
At least you can run Art filters with full resolution and the original RAW image, not a destructive half quality jpeg.
Could be useful especially for shooting Marco with focus stacking….
That’s all very nice and everything. But while Panasonic is working on firmware updates, how about they implement a lock or press & hold for the Disp button on all their cameras? Accidental pressing of the Disp button – followed by having to press it again six times to get back to the original setting – has to be the number one complaint about Panasonic controls. I’ve even emailed Panasonic directly asking them to fix this.
V-Log or Post Focus ? I choose V-Log
Här hardi mina tester sedan jag har uppdaterat min GH4. Her you go. Shoot testing my GH4 with the V-LOG. Well done Panasonic. There is much more you can do with planed shooting. I’m still working on the test, side by side with RED and will get back soon with the result.
