The LuxGear Follow Focus Gear Ring from Cool-Lux is a seamless lens gear for lenses with a focus-barrel diameter of 78 to 79.9mm. It features standard 0.8-mod/32-pitch geared teeth that makes it compatible with cine-style follow focus systems. The gear slides onto your focus ring from the front or back of the lens and holds securely without the clamps, screws or zip ties that can interfere with your follow focus and limit your lens's rotation.

This gear is precision molded in high-durometer silicone and is available in 16 sizes, each designed to fit lenses within a two-millimeter diameter range, ensuring a tight compression fit on the focus barrel. To find the appropriate sized gear for your lens, please see the lens compatibility chart and sizing tools accessible by clicking on "Guides & Manuals."
