I have been detecting a horizontal noise pattern that is pretty significant when using Slog-3 between ISO's 1600 and 10000. Once hitting 12800 the noise pattern seems to clean up significantly.
See my test video here: https://youtu.be/aB7WgSGY0YU
Youtube compression makes it hard to see, so I have the raw video available for DL here: https://www.dropbox.com/s/vsij4c1dvhvkoq6/A7sII_NoiseTest2.MP4?dl=0
The video seems much cleaner using Cine2 gamma here: https://youtu.be/d2yybsokLkc
Is anyone else having this problem? I have a replacement body showing up tomorrow and I will run another test to see if maybe I got a lemon.
P.S. This is after installing the new firmware released on the 20th that that was meant to fix the sun spot problem some people were having.
