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.
