See my Fujifilm GFX wish list.

I set out to compare ISO 100 to ISO 12800 using exposures that were both 3 stops underexposed (as per RawDigger), making for equivalent ISO of 800 and 102400.

In preparing this piece, I ran into some strange behavior, discussed in detail.

In my review of the Fujifilm GFX system in Medium Format :

ISO 100 Pushed and ISO 12800 in Low Light (Riparian Tree by Creek)

Includes images at up to full resolution plus RawDigger data, Fujifilm GFX rear LCD images, ACR Settings and ISO 12800 with and without chroma noise reduction.

f8 @ 8.0 sec, ISO 12800; 2017-03-07 18:32:18
GFX 50S + Fujifilm GF 63mm f/2.8 R WR @ 51.8mm equiv (63mm)
