The Libec Zoom Control for DV Cameras is a universal controller for LANC and Panasonic MiniDV or HDV cameras, with a converter switch for LANC (most Sony and Canon cameras) and Panasonic. A sensitive thumb switch allows for variable-zoom speed from slow to fast. The zoom lever allows you to zoom out to wide-angle or zoom in to telephoto. Lightweight and compact, this unit has an outlet cable and can be clamped on tripod pan handles, monopods, stabilizers, and other such devices.
