Popular with operators around the world, the FS7 / FX9 adjustable arm with Grip Remote Control transformed shooting on the go, and now with GP-VR100, we've made it even better. The arm's length is easily adjustable at the turn of a knob, while another knob at the joint adjusts the angle. Once perfectly adjusted for shooting from your shoulder or waist, Sony's Grip Remote Control puts all the important controls at your fingertips with Zoom, Start / Stop and a range of Assign controls, including a dial you can use to adjust Iris. You can operate the camera without taking your hand off the grip. The unit can control basic camera shooting operations (recording start / stop, zoom, etc.). You can operate functions assigned on the camera using the ASSIGN (assignable) button, assignable dial, and multi selector.
