The Zoom Servo Drives set instantaneously control commands that come from a SONY FS5 / FS7 camera or any other LANC-compatible zoom device.

The operator may choose from four different zoom modes: EB / Documentary, Live / Hardcut, Silent, and Direct Mode. To ensure liquid zooming with soft stopping the “Soft Ramping“ gently slows down the movement of the lens.

A wide variety of power cables with straight and angled plugs are available for all types of camera power out sockets and batteries including camera run / stop functionality.
