Product description

• FF-4 Basic Follow Focus Unit (Black Edition) The sleek, black-finished ARRI FF-4 Basic Follow Focus Unit consists of a single-sided follow focus with one standard knob. This robust, economical unit slides onto a pair of lightweight 15mm rods (rods not included). The FF-4 is designed with a 1:2 knob-to-gear ratio for smooth, accurate focus pulls on a variety of lenses. A required focus gear is not included with this unit. The FF-4 features a modular design that is compatible with most ARRI follow focus accessories such as whips, speed cranks, and knob accessories (available separately). One flat marking disk is included with the FF-4 Basic Unit. Note: A BA-2/3 adapter is required for use with a studio bridge plate
