i have noticed something peculiar.

High ISO is a different beast to handle. A7s A7sII GH5s all at high ISO not only and obviously loose dynamic range, but people trend to focus more on mid tones, and clip the highlight with no hesitation. This gives shit image, bad handling of it.

One must shoot for low light knowing that post would be used to extract the shadow detail at an extent, but clip soooo much the highlights is stupid and bad looking.

This Japan video speaks for itself.

So now that Gh5s has 4k 60p 8bit....its more than obvious that it can pull 4k 60p 10 bit. More proof on Eva 1 gh5 Gh5s g9 same lsi.

Hack this camera, anyone. I assure 14 bit video

1. In all modes, Dual Native iso is 400 and 2500 in all picture profile modes. What changes is the base iso depending on which profile you're using. Here is what I have been told:
   Log or HLG low range is 320-1600, high range is 1600-25600, HLG can use extended high ISO
   with other profiles no range is 160-800 and high range is 800-51200
   Shooting under the native Dual ISOs comes with reduced Dynamic range, but results in cleaner footage at a loss of highlight detail.
2. ETC the 1080 looks to be a double crop of the full view, I don't believe 4K has any etc mode due to the multi aspect sensor. It didn't seem to be offered in any of the modes I tried.
3. Could you please private message me regarding the high contract scene and I will try and capture something for you specifically.

I have to give the camera back to Panasonic tomorrow unfortunately as it is going to be used on an upcoming TV show!

That last test shows the better Face detect AF but hunting still prevails. See the erratic breathing of the focus on the background. Still a marked improvement from the terrible GH5 performance here.

"posers" or "people who are maybe shooting something different than what you're shooting." One of the two.

It's just a simple fact that IBIS is very useful especially to the level of client buying these cameras. If they perceived it as such a problem they should have invented a way to lock down the sensor. I can't believe that it can't be done. That being said I never heard anyone say "that damn IBIS is screwing me up wish they would remove it". So there justification just comes off as excuses. Also if your going to go this route you need to make remote focusing work as good or better than Canon especially when your AFC is below par. This way you can still use lite gimbals with these small cameras instead of big heavy Gimbals with motorized follow focus defeating the advantage of the small camera.
