The ARRI Follow Focus FF-5, a completely modular, film style follow focus. Designed specifically for lenses with a smaller diameter focus barrel, the FF-5’s longer swing arm ensures proper gear position on the focus ring and a lower gear ratio for a more exacting focus pull on smaller diameter lenses or those with compressed focus scales. The FF-5 integral snap-on mechanism locks to 15mm lightweight support rods and can be adapted to work with ARRI standard 19mm bridge plate support rods.
