The VZPGC 8-pin Canon Zoom Control provides remote zoom control for most Canon professional video lenses and it will clamp to any tripod handle, jib, or support bar with a unique offset swivel clamp for adjusting the angle of operation. The pistol-grip design allows left- or righ-handed operation. The PG-C features a dual-variable system for versatile, precise control of zoom speed. Set the maximum desired speed on the dial (located in a `trigger' position), then use the pressure-sensitive rocker to vary the speed from a crawl all the way up to the preset max. Alternatively, depress the rocker fully and roll the dial with your index finger to ramp the speed up.
