The black Type-A Pro Thumb Grip for Mirrorless Digital Cameras from Fotodiox was designed to slide into a universal hot shoe, to create an additional grip on the camera. The Thumb Grip protrudes from the back of the hot shoe, providing a secure grip with convenient access to the camera's controls. The grip is made from anodized aluminum.
