If you have a Fuji X100vi I'm jealous! But I have the Fuji X100v and it's almost identical - close enough that the SMALLRIG Thumb Grip fits perfectly.

This is the special engraved thumb grip, as you'll see in the video.

It feels great and really makes the camera easier to hold. Looks cool too! And the little red soft release shutter button looks very cool - you'll look super professional using these two items! Hey, my photos may still be lousy, but I look the part!
