MFC-1 follow focus for DSLR, ENG and small Cine style lenses, with a gear ratio of 1:1.5, including hard stop system . The MFC-1 is a very compact, high quality and light weighted follow focus system. The follow focus clips on 15 mm LWS rails (or optional 19 mm rails by using a 19 mm to 15 mm adapter), and attaches to the lens from underneath. The follow focus is height adjustable and the rotation direction can be reversed. A various amount of drive gears can be mounted to both sides of the MFC-1 gear box. An intelligent double hard stop system is integrated in the follow focus knob, but it's also possible to use the MFC-1 without the use of hard stops.
