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.

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 Leica lenses.
