The ARRI FF-5 Follow Focus features a longer focus gear 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, or cine lenses with a compressed focus scale.
The FF-5 can be mounted directly onto lightweight rods (15mm LWS) via a snap-on locking mechanism, ensuring a simple and fast setup on the set. With a studio adapter, it can also be mounted on 19mm studio rod configurations. The FF-5 is compatible with driver gears for all popular types of HD and cine lenses. The drive gears mount on either side of the swing arm for maximum adaptability.
