>>4402782Yep, even at the highest ISOs, a larger sensor with more and larger pixels absorbs more information. It's obvious at high ISOs, but at low ISOs that extra accuracy means they capture finer and finer tonal gradations and give the image a subtly better and more realistic look. On zooming in it's minor but it has a global effect on the image that makes it appear like it comes to life even at smaller print sizes and on screen displays.
The GFX100S can go up to ISO 102400, still have a clear image, and need some extra pushing in post past that to look even half as bad as the smaller sensors would at 56,000 btw
