VariZoom Rock Compact Zoom Control

The Rock strips VariZoom's zoom control down to its lightest, most affordable form: a compact ABS housing with a pressure-sensitive side-to-side rocker and a speed-limiter knob, built for mounting on a jib, stabilizer, or any rig where every ounce counts. It clamps to a bar up to 1.25 in in diameter and runs on a 40 in cord to the lens.

The Rock-C and Rock-F cover 8-pin Canon and Fujinon professional zoom lenses respectively. The Rock-C20 is built for Canon's 20-pin CN-E 18-80mm and 70-200mm cine-servo lenses and most other 20-pin Canon broadcast glass, and adds record and one-shot autofocus buttons that the 8-pin versions don't carry.
