How interested are you in a GH6 anymore?

Phase detect is not without its flaws and DFD has the potential to be better someday. We shall see if this is that day.

If the notion of the camera cartel is legitimate, it seems Panasonic has done the best it can with DFD. While it may not be enough for some, it seems it would be as good as it possibly could be. Likely better than any of us would have expected from DFD right now, anyway. The samples in the non private video were not perfect nor as good as the best AF out there, but they were not bad. This one has been beaten to death and no doubt, it will be a make it or break it feature for many. It is what it is. All we can do is wait for more sample footage and reviews in 5 days.

To be fair, the OM-1 is missing 422, but the 4K 60P 10 bit h.265 looked very good as did the footage in low light looked pretty decent. I'm not sure either camera GH6 or OM-1 floats my boat over the GH5S on a gimbal and praying the DFD holds focus on the bride. The GH6 has high bit rate 10b 422 modes which should look good but I've been through at least 3 iterations of DFD and I'm done with it. The OM-1 video doesn't seem to suffer too badly from lack of 422 though and the long GOP modes would be media friendly. There's 12 bit 444 raw to an optional recorder through a mini-HDMI that doesn't excite me, but I guess for someone with the patience for Rube Goldberg, there's that. Both cameras have gone under the cripple knife in my opinion, but you're right; I haven't been fair to the GH6 but DFD has me gaggling with hate.

So, it sounds like they are doing a bit of digital magic like what is being used on smartphones. Suppressing more noise via even better processing, and extending dynamic range via digital trickery. If it works really well I am for it, but I am a little skeptical... and I would like to know what the dynamic range of the sensor is without any such trickery. If it actually resolved 13 stops and looks indistinguishable from other cameras resolving that, it's good enough for me to be an A-camera.
Yikes, this could be inconvenient. But I suppose no more inconvenient than shooting on a full frame sensor, it may just indicate that higher stopping power ND filters will be needed if outdoors in very bright sunlight and wanting to shoot at F/2.8 or wider.
It isn't exactly magic and a common way photography creates HDR. Totally valid way to extend dynamic range in a camera. Its just not always possible with video because of howe fast the sensor has to readout for just normal video. There was nothing left to be able to pull off something like this until now.
Its almost always been a given that log will likely need ND filters. Even without shooting log I'm not sure how anybody gets away with shooting video without some level of ND filtering. 2000 ISO is a good sign we may be finally getting full V log on the GH6 and can kiss V-log L goodbye forever. We hope.

PS. Side note - this looks to be a totally new, previously unannounced, sensor. Which may explain the delay in the GH-6 introduction. Whoever made the sensor had to do it to Panasonic's specs. It's also likely that Panasonic revised the requirements somewhere along the way. It's also very likely that the company wasn't sure when the sensor was going to be available and was forced into the GH5MKII as the interim solution. Ah, the best laid plans.
The 100 MPX is likely off a pixel shift rather than off a Quad Bayer singe frame but the 4X in-camera composite seems to be possible these days. Once again, one needs to interpolate the various frames to avoid digital "smudges" and, for that, one needs some beefy processing but it can be done. OM-1, as we have discussed earlier, does it as well. Maybe GH-6 will do it even better.

And we’ve got a full spec 8 page PDF leak on scribD:
https://photorumors.com/2022/02/16/p...ed-online/amp/
looks like the OLED EVF is same as GH5 at 3.68 million dots (so not as good as S1H 5.7 million) and the LCD screen seems it is slightly smaller than GH5, coming in at 3.0” instead of 3.2”. However it’s an increase in pixels up from 1.6 million to 1.84 million. So perhaps they did this to make the screen sharper and maybe brighter?
anyway, lots more specs there… have at it…
