Fujifilm disrupted the medium format camera market when they released the Fujifilm GFX50S and followed it with the 50R. In fact Fujifilm was so far ahead of the competition that Hasselbad quickly abandoned the original X1D and followed it with the X1D II, which by most accounts is a significant improvement over the original, but we haven’t seen a lot of comparisons. Above is a pretty good one and I have summarized it below:
X1D II is mainly screen driven and small
GFX50R has a lot of dials like a giant rangefinder
Both have the same Sony Sensor
The color science of each company is what will make the difference
Fujifilm much warmer and a little darker
Hasselblad can be a little warm sometimes too
An incredible amount of detail and tonality from both
Hasselblad has a more true to life tonality, but the Fujifilm has a very nice warm to cool tonality
Both have great color science
Hasselblad has richer color in high ISO
High ISO is very similar but the softer grain in the Hasselblad
Hasselblad can flash sync up to 1/2000th but Fujifilm you cannot without HSS otherwise you’re stuck at 1/125th
If you shoot with strobes the Hasselblad might be the better camera for you
When you mess with the color you can make them look similar
When recovering shadows the Fujifilm gets a little green, but the Hasselblad gets magenta splotches
Fujifilm has sharper grain
Toss up with dynamic range, with maybe an edge to Fujifilm for holding detail in the shadows
Fujifilm is big with big lenses with a nice tactile nature
Hasselblad is small and compact like a true mirrorless platform, but wish it had more dials
Fujifilm fastest AF
Hasselblad slow hunting AF
Hasselblad has great color
If your work is slow and deliberate Hasselblad might be your preference
If you need speed Fujifilm is the way to go
Both have strong image quality, detail, and color
Hard to pick a winner unless you shoot a lot of strobes
