The Arri FF-5 HD is a follow focus kit including an follow focus base, left- and right-sided standard focus knobs, one speed crank, and 10 marking disks. The FF-5 snaps onto 15mm lightweight support rods, or use the included bridge-plate adapter to mount to 19mm studio rod systems.

With a gear ratio of 1:1, the FF-5 HD is designed for smaller video lenses, with one turn of the focus knob resulting in one turn of the focus gear.
