The Movo Photo HSG-4 assures you of a firm grasp of your camera while out shooting. The padded hand cushion is comfortable and provides support when the shot appears. Rather than have your camera dangling from a long strap, this hand grip keeps your DSLR firmly in your hand so when you're ready to shoot, all you need to do is raise the camera to eye level and shoot. It attaches to your camera by first attaching its plastic plate with 1/4-20 thumb screw to your camera's tripod socket. Then, by back buckling the other end to your camera's strap lug, it locks into place
