This 78 to 80mm 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 78 to 80mm diameter size are etched inside of the ring to quickly find the correct ring for your lens.
