Q: 1. 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 .

Q: 4. Hello and thanks in advance for the help to however is going replay; I do have 2 Sony lens ( SONY FE 24-70/2.8 GM LENS and Sony FE 16-35mm f/2.8 GM (G Master) i like to use the Tilta M motor but I don't know if this ring will be spinning on the lens or it will be mooving or is the best solution comparing to the soft follow focus ring? Once more thanks Fabry

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

Q: 5. Will this ring fit the focus ring on a canon 100-400 L IS ii? I realize the outer focus ring diameter is 94mm… but after measuring with the Cool Lux Gear sizing key (paper print out), the inner diameter of the focus ring falls in the 90 to 91.9mm zone. Would it possibiy work?

A: We do not recommend using this ring as it may be too small for the lens.

A: No. It is too small. The Sigma Art Lens diameter is 88.6mm and this ring is for 82-83.9 mm lenses.

Q: 7. Sigma 50-100mm f/1.8 DC HSM Art Lens for Canon EF... which size?
