The Mini Follow Focus MFF-2 Cine Base from ARRI is a main building block of the MFF-2 follow focus system. This sturdy, single-sided unit snaps onto any 15mm rod lightweight support (not included). The Cine Base is designed with a 2:1 knob-to-gear ratio for quick but smooth focus pulls on cine-style lenses, with their typically large range of focus barrel rotation. The base's reversing feature can be used to maintain the standard direction of the focusing knob when using Nikon and Leica lenses.

The modular design of the MFF-2 enables you to build the follow focus to suit your needs. A choice of three compatible ARRI focus knobs is available—standard, two-speed, or hard-stop (all left-sided). Gears come in various sizes and pitches to work with different lens barrel sizes and gear ring pitches. Focus knobs and lens gears are not included with the MFF-2 Cine Base.

Q: 1. Is the focusing gear reversible to the opposite side, so you can have opposite function?

A: No, this does not reverse the wheels. Nikkor lens shooters will have to look elsewhere.

Q: 2. Can you reverse the gear? Right now I turn the wheel away from me, and focus becomes closer. I'd like the opposite to happen....

A: The SmallRig F40 mini Follow Focus is designed to be a universal follow focus that can be used when mounted on 15mm rods with cinema, mirrorless or DSLR cameras. Considering the design of the Bolex 16 and the age of the camera, the follow focus would not be compatible.
