The Grip Belt GB-001 from Fujifilm is compatible with many models in their X-series of digital cameras, as well as their FinePix HS50EXR camera. It is a comfortable padded strap that wraps around the back of your hand to provide a more secure hold when gripping the camera, allowing you to firmly hold it in just one hand. The grip belt also works with select hand grips and a battery grip for the compatible cameras.
