A handful
The GFX100 is roughly the size and weight of the Nikon D5.
A more digital design
Like pro DSLRs, the GFX100 uses buttons to cycle among modes.
Settings readout
There are various different views for this display, including virtual shutter-speed and ISO-sensitivity dials that seem kind of superfluous. You switch the display layout with one of the buttons on the top right and cycle among the modes (manual, shutter priority and so on) with the other.
Movies and stills
The dial on the left shoulder controls the shooting type, such as stills or video.
Back
Aside from the secondary settings readout on the base of the camera -- similar to that on pro DSLRs like the Nikon D5 -- the rest of the controls are typical Fujifilm: AF- and AE-lock buttons, a navigation joystick, drive-mode switch, quick-menu button (in my least favorite place, on the thumb rest) and so on.
Multiangle tilting touch screen
While it's nice to have the flexibility to orient the LCD in multiple ways, I find folding out the titling display a bit awkward, like I'm doing origami.
Dual batteries
Mirrorless cameras have pretty bad battery life, so the GFX100 accommodates two.
Connections
The camera has mic and headphone jacks, USB-C, micro HDMI and and a remote connection.
Dual SD card slots
You really need to use fast cards in the GFX100, not just for the video recording as Fujifilm recommends (V60 or V90), but because playing back the huge images is slow going if the card isn't speedy.
Vertical grip
Unlike Fujifilm's other cameras, the GFX100 has a built-in vertical/battery grip. Since the viewfinder isn't in the center, some people may not like shooting with it, though.
Sturdy grip
The camera and the lenses are pretty heavy, but the grip is deep enough to give you a stable hold.
