The Magnus VC-20-SCP Zoom Controller for Canon, Panasonic, Sony provides record and zoom control for all LANC-equipped Canon, Panasonic, and Sony camcorders. An included 22.5" long control cable connects into the controller on one end and into the camcorder's LANC port on the other. You can also use this controller with Sony consumer cameras via an optional Magnus ACM-SAVR AVR adapter cable.

A built-in mounting clamp allows attaching the controller to your tripod pan handle so you can zoom and pan with one hand and achieve a fluid look. The clamp opens up to 1.25" and also fits jibs, tubes, pipes, and bars. Zoom is regulated by a pressure-sensitive rocker switch that produces faster or slower control depending on how hard or gentle you press it. For tape-based cameras, a REC/RET button works together with a REC/RET switch to let you return to the last record position.
