Finally got tired of my follow focus slipping on a smooth lens barrel. This ring’s seamless silicone grips tight without any adhesive or crease, and the 0.8 MOD teeth engage cleanly every time I rack focus.

Wrapped this around my vintage 50mm and it instantly made pulling focus with my follow focus smooth and precise. The silicone grips the lens tightly without slipping, even during a full day of shooting. Exactly what I needed to make my old glass work with modern rig gear.

Took a chance on this for my manual focus lenses and the grip is much tighter than I expected—no slipping at all. It's thin enough that the follow focus gears still catch perfectly. Exactly what I needed for video work.
