FUJIFILM MHG-GFX 100S II Metal Hand Grip

It does fit 50S II

Unfortunately, the FUJIFILM MHG-GFX 100S Metal Hand Grip is not compatible with the GFX 100 II.

It attaches to the base of the camera and retains access to the battery and memory card compartment.

IT IS TRUE - no access to the battery while the grip is mounted... I just received my handgrip yesterday... It is very light and fits well on my Really Right Stuff tripod. There is a 1/4-20 screw socket. I wish there was access to the battery compartment. It is easy to attach and remove with a thumbscrew with a handle that flips up. Very secure, it fits into the curves of the bottom of the camera so once attached it is solid. The handgrip fits my hand much better with the little extension it provides.

No there is no option to attach a strap hook

The FUJIFILM MHG-GFX 100S Metal Hand Grip will fit the FUJIFILM GFX 100S II Medium Format Mirrorless Camera perfectly; however, please be aware that the battery compartment will be disable. We recomend connecting your camera through the USB-C port to power the unit.

On other Fujifilm grips the grip is left open/not covered in that area for access to battery and memory card. We don't have this item in stock yet but it should follow suit with the others.

No this is Arca type plate , it can mount on any Arca compatible tripod heads
