TILTA Seamless Focus Gear Ring for 72mm to 74mm Lens

Tilta’s Seamless Focus Gear Rings allows you to add 0.8 MOD gears to a compatible lens for use with cine follow focuses. The seamless version is designed with an improvement over Tilta’s earlier gear rings in that it’s fully closed and requires no screws in order to be secured to the lens. As a result, it attaches to the lens more easily and provides evenly distributed pressure while ensuring zero drifting and accurate focus. It’s made of durable, flexible rubber, attaches firmly, and works silent and smooth along 360° of rotation.

There are 14 different sizes to choose from for different lenses. Please see the list of lenses below and the compatible ring size next to each one, as provided by Tilta. Other lenses may be compatible as well, but the below list has been confirmed by Tilta.
