VZ-ROCK-C100, Variable-Speed Focus Ctrl
This is the only controller of its kind for the Canon C100. You can control focus precisely with our custom variable-speed rocker and also start/stop record, power the camera on/off, control iris up/down, and 'push auto iris.' Whether you need to make very fine focal adjustments or quickly shift from near to far, the variable speed control smoothly adjusts the focus without any chatter or jumpy response. This controller can also be operated from up to 300 feet with optional cables.
