Q: 4. 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 .
