The next medium format camera from Fujifilm is expected to offer an even higher resolution than the expensive Phase One XF IQ4. According to the latest rumors from a reliable source, Fujifilm is currently developing a GFX camera with a 180MP medium format sensor.
Fixed 35, but with the larger sensor it’ll behave more like a 28mm full frame.
I brought the RF up just because of its size. Those other GFX cameras are absolute units once they have a lens on.
