The UFF-1 Universal Follow Focus (Pro) fits all three major rod standards — 15mm LWS, 15mm studio and 19mm studio — without rod adapters, using movable rod clamps that lock into marked positions along the bridge. A swinging arm accommodates lenses of multiple sizes and adds extra reach when working on the studio rod standards, and the design is fully double-sided: drive gears can be mounted to either side of the arm, and the arm itself can be mounted to either side of the gear drive. The Pro version is built out with the accessories needed to pull focus across a range of setups, including 10 marking disks, two hard-stop discs, a focus whip and crank, 5 focus drive gears (0.5 MOD, 0.6 MOD, small 0.8 MOD, large 0.8 MOD and friction), and a 75mm hand-wheel extension.
