The LuxGear Follow Focus Gear Ring from Cool-Lux is a seamless lens gear for lenses with a focus-barrel diameter of 68 to 69.9mm. 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."

A: I have several Nikon Nikkor lenses and purchased a few Cool-Lux LuxGears to fit them.

Q: 7. I have a Fuji XF 50-140mm 2.8 lens, it's a 72mm sized lens. Will this fit it?

A: The FUJIFILM XF 50-140mm f/2.8 R LM OIS WR Lens outer diameter at its widest point is 82.9mm. This ring will not fit then. The 72mm dimension refers only to what size filter will screw on to the front. We would suggest this one Cool-Lux LuxGear Follow Focus Gear Ring (82 to 83.9mm) B&H # COLG8283. If that does not fit you might try these adjustable rings. Wide Open Camera Universal Lens Gear B&H # WILU or ikan 2.5-4.25" Diameter Adjustable Lens Zip Gears (3 Pack) B&H # IKELEFGKLG .
