This Universal Focus Gear Ring from Tilta allows you to add an adjustable 0.8 MOD gear to a compatible lens for use with cine FIZ motors. This universal ring fits virtually all lenses of just about any outer diameter, and it is an ideal add-on for photo lenses that don't have built-in cine gearing.

The gear comes in a black color, and there are optional other colors that can be used with different lenses to differentiate them in your kit. It is made of durable, flexible material that attaches firmly around the lens, and it can be adjusted and secured using the clasp lock.
