Lensmate Thumb Grip for Fujifilm X100T - Black Note that this will not fit the X100F, we will be working on a new Thumbrest once the X100F is released. No-compromise design specifically for the Fujifilm X100T, with ideal length and curve geometry. Retains access to all controls while preventing unintentional button presses. Integrated silicone insert provides thumb grip and bumper between camera body and thumb grip. Hidden silicone insert in hot shoe tab provides resistance to unintentional ejection. Machined from 6061 T6 aircraft aluminum, bead blasted for texture, then anodized silver or black for an attractive finish. We suggest using our custom soft release button, shown in product photo, with the Lensmate X100T Thumbrest for a more relaxed and ergonomic index finger position (with the finger draped over the button, usually not using the finger tip).
