With SmallRig Seamless Focus Gear Ring 75 to 77mm, you add a focus gear ring to your 75 to 77mm lens without the extra slack or screws required.
The seamless ring allows you to use standard 0.8 MOD cine gears on a compatible lens for use with cine follow focuses. This 75 to 77mm size fits virtually all lenses of the same outer diameter, and it is compatible with a variety of follow focus motors such as the SmallRig Mini Follow Focus.

It attaches easily to the lens and provides evenly distributed pressure while ensuring no distortion, less noise than zip-tie style rings, and accurate focus. It’s made of durable, flexible rubber, attaches firmly, and provides smooth 360° of rotation. The MOD rating and 75 to 77mm diameter size are etched inside of the ring to quickly find the correct ring for your lens.
