The RFGD1915M is a professional dual wheel follow focus mechanism from Cavision. Using an entirely geared transmission, it provides a convenient, quick and precise method for controlling your camera's zoom and focus using a knob on either side of the camera without the need to constantly reach over to the front of the lens. Follow focus systems have become a staple of professional photographers and videographers needing to adjust a camera's zoom or focus within a shot; hence the name "follow focus."
The RFGD1915M for Film/Cine lenses comes with a 34mm gear. An optional 28mm or 44mm gear is also available.
Note:
Support rods and lens gear rings not included.
