The FF-5 has a longer swing arm for better gear positioning with HD lenses. A lower gear ratio is also better suited to the smaller lens diameter of HD lenses and/or cine lenses with a compressed focus scale. The FF-5 can be mounted directly onto lightweight rods through a snap-on mechanism ensuring simple and fast setup on the set. With an adapter it can also be snapped onto 15 or 19mm support rods. The FF-5 can be equipped with driver gears for all popular types of HD and cine lenses. The drive gears can be attached on both sides of the swing arm.
