ARRI’s FF-5 Cine Follow Focus Base is designed to snap onto a pair of 15 or 19mm lightweight rods. An adapter is required to use the FF-5 Cine with 15 or 19mm studio rod systems (not included). This base unit of the FF-5 does not come with any knobs or lens gears (available separately).
The FF-5 Cine Base is designed for cine-style lenses. With a gear ratio of 2:1, one turn of the focus knob results in two turns of the focus gear. This gear ratio suits the generously-spaced focus marks found on most cine lenses.
