This is a remote zoom & focus controller for most Canon camcorders with a LANC connection. This control unit can also power the camera on & off, controls zoom speed and provides a record button as well. Cable supports two connector styles. We used it with a Canon XF 305 and it worked great. It is in great condition. Thanks for looking.
