BHphoto here: Complete Comparison Fujifilm GFX100 vs Sony A7III vs Nikon Z7 vs Canon EOS 5DS R
Now you say, it is unfair to compare it with full frame. And yes, it is. But it is also unfair to compare it to other medium format cameras.
It’s the first medium format camera with IBIS, it’s mirrorless, it’s fast, and it has the size of a full frame DSLR with integrated grip, such as the Nikon D5 and Canon 1Dx MK II.
And if you think $10,000 is too much for the Fujifilm GFX100, then look around and you’ll discover that a Mamiya Leaf with 50MP 44×33 sensor, which is inferior in every regard to the GFX100, will cost you $24,000!
The Fujifilm GFX100 simply sets itself in a new territory.
