Movcam Flexible Gear Ring is a universal ring for most follow-focus devices and for any lens with a diameter up to 104mm. The ring features standard 0.8-pitch, wear-resistant teeth. To prevent it from coming loose, the gear ring has an inelastic length and a unique locking mechanism that keeps it in place, snugly hugging your lens so you can rack smoothly.
