The VZROCKC20 works extremely well for a variety of applications, as it offers smooth, tight zoom control via a speed limiter dial and a pressure-sensitive variable rocker, start/stop record button, and one-shot AF all in a compact, lightweight form factor. The controller has a 40” 20-pin cable that plugs into the remote port on the underside of the lens, allowing you to incorporate it into use on stabilizers, gimbals, jibs, or any other application where size and weight are critical. . 10ft. and 20ft. extension cables are also available for purchase separately. This item comes with a limited 2 year manufacturer’s warranty.
