The VZROCK-C100 LANC Focus Control from VariZoom supports the LANC protocol and is specifically designed to provide you with a focus rocker and f-stop up/down buttons for use with cameras such as the Canon C100 and C300 cameras in EF mount. The controller interfaces with the camera and uses the built-in motors of the EF mount lenses to drive focus and iris. The rocker supports both the Mark I and Mark II versions of the C100 and C300, but does not support the PL mount version.
It allows you to control focus with the variable-speed rocker and features camera on/off, a camera record/low battery indicator LED, iris up/down, buttons as well as push auto iris controls. The unit features a built-in clamp for your tripod handle or a stand, and can control your camera from up to 300 feet away by using optional extension cables.
