The ProMaster Remote Pistol Grip is a comfortable convenient handle with optional remote shutter release function. It is ideal when using your camera for recording video. The ergonomic design of the pistol-style grip makes for comfortable operation. The Remote Pistol Grip mounts to the bottom of most any camera, camcorder or spotting scope that has a 1/4 - 20 mounting socket. The convenient thumbwheel makes attaching the grip simple and quick. The accessory port on the grip allows you to use an optional ProMaster Camera Release Cable which when attached to your camera offers remote control of the autofocus and shutter release functions of your camera.
