for 15 mm Lightweight Support - designed with lighter
cameras in mind and compatible with all available
ARRI lens gears and focus knobs.
Cine has a gear ratio of 2:1 for cine style lenses,
which means one turn of the focus knob will result
in two turns of thefocus gear. This gear ratio is common
to all classic follow focus units from ARRI (FF-3, FF-4, etc.) and
is traditionally suited to cine lenses such as Ultra Primes,
Compact Primes, Alura Zooms, Angenieux Zooms, etc...
