Review Summary

I use these gears along with the Red Rock Follow Focus v2 + Shoulder Mount to control my Canon lenses and they work wonderfully. The gear fits around the focus ring of the lens and are tightened with the included thumbscrews. The inner ring of the gear grips firmly and doesn't slip when aligned correctly. It takes less than a minute to setup. With the extended surface area added to the ring, focusing becomes much more precise. Definitely recommended!
