The LuxGear Follow Focus Gear Ring from Cool-Lux is a seamless lens gear for lenses with a focus-barrel diameter of 90 to 91.9mm. 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: Tilta makes their own rings which are measured for use with these specific lenses. For both the Sony FE 24-70mm f/2.8 GM II Lens and Sony FE 16-35mm f/2.8 GM Lens, Tilta recommends the Tilta Seamless Focus Gear Ring (81 to 83mm). This is what we would recommend for use with your set up. https://bhpho.to/3EYPODd

A: It will not. The Sigma 24-105mm, BH #SI241054C, has an 88.6mm front diameter. It is too large for this gear ring. Instead you will need BH #COLG8889 which is for lenses between 88 to 89.9mm. https://bhpho.to/3bnrtEK

Q: 8. 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 .
