The hand grip allows an additional 8mm clearance from the camera body base to prevent large-diameter lenses such as the XF23mm and XF55-200mm from interfering with the tripod head.
It is designed specifically to allow users to open the camera's battery cover for speedy access to the battery or memory card even while the grip is mounted on a tripod.
Its tripod-mounting screw hole positioned so that the rotation axis of the tripod is aligned with the optical axis of the lens to enable panning and framing free of rotation displacement. The base part also features a 38mm-wide protrusion that acts as a quick-release dovetail plate for use with a dovetail tripod mount.
