Lensmate
Fujifilm X-T2 Thumbrest in Black
Also fits X-T1
Designed for use with the Fujifilm X-T1 or X-T2, this Fujifilm X-T2 Thumbrest from Lensmate features the ideal length and curve geometry for comfortable use. The sculpted thumbrest relaxes your grip on the camera, reduces camera shake, and allows for slower shutter speeds. It will also make one handed operation easier, and help to prevent unintentional button presses.
This camera specific design retains access to all controls, while an integrated silicone insert provides both thumb grip and bumper between the rest and the camera body. Machined out of solid 6061 aluminum rod, it is then bead blasted for texture and anodized for a tough finish.
To use the thumbrest with the extended eye cup, press the right hand side of the eye cup down and to the left, while sliding the thumbrest into the hot shoe housing. Do the reverse when uninstalling the thumbrest.
