The Libec ZC-LP LANC Zoom Control enables remote REC start/stop and zoom control for LANC-equipped Sony, Canon, and Panasonic camcorders (certain models may have limited or no compatibility). It features a 2.3′ cable terminated with a 2.5mm sub mini plug for camera connection. The control unit features a clamp that easily mounts onto pipes up to 1.8″ in diameter. It comes with a converter switch that allows you to set the camera type to LANC or Panasonic. The zoom speed can be adjusted by tilting the rocker. The unit’s inverted switch allows you to control and reverse the zoom direction.
