Canon 1754C001AA (175/4C001AA, 175-4C001AA, 175 4C00/1AA, 175 4C00-1AA) (SG1, SG 1, SG/1) SG-1 Shoulder-Style Grip Unit
The SG-1 Shoulder-Style Grip Unit from Canon enables you to control your EF lenses like regular ENG video lenses. It features a grip/rocker assembly that mounts on the rods of the separately available SU-15 Shoulder Support Unit. With it, you can control record start/stop, iris/aperture, and - if supported by the lens - zoom. It connects to the camera via a 12-pin connector, which also supplies the units power.
