The Libec ZFC-L LANC Zoom and Focus Control enables remote REC start/stop, zoom, and focus control for LANC-equipped Canon and Sony camcorders (certain models may have limited or no compatibility). It connects to the camcorder via a 2.3′ long cable terminated with a 2.5mm sub mini plug.

The zoom speed can adjusted by tilting the rocker. Its inverted switch allows you to control the zoom direction. The control unit features a clamp that easily mounts onto pipes up to 1.8″ in diameter.
