SmallRig Seamless Focus Gear Ring (62.5mm to 64.5mm) - 3291

The perfect ring to fit the zoom ring of a Sony 24-70 f2.8 GM. Easy to slide on or off and tight enough that it doesn’t slip under a turning focus motor.

Fits the focus ring perfectly. Just the right width also. Easy to install. A+

These work great with the RS4 Pro focus motor and my Canon lenses. Slip it on and set manual focus endpoints on the gimbal and it's done and ready to go. The 81-83 fits the RF 24-105L F4 like a glove. I like how much quicker and easier it is to find the focus ring by feel so I don't plan to take it off. For both the 35 1.8 IS Macro STM and 24 1.8 IS Macro STM the 72-74 fits snugly. The 75-77 will also fit those lenses but less snug. The focus ring is so smooth on all my Canon lenses it doesn't have to grip too tightly to move the ring so either one works but I like the tighter one for keeping on the lens full time. I plan to keep a 72-74 on both. I plan to get one for every lens that's reasonable to use with my gimbal. These are a great deal and head and shoulders above the clip on gear ring that comes with most motors.

This fits snugly instead of the universal gear ring for non cinema lens...better option for your manual focus puller.

Works great with ease.

My lens focus ring has a diameter of 82mm, this fits perfectly. You can't go wrong with this.

It interfaces with DJI Focus Pro Motor teeth great! For only $3 it makes my Sigma 17-40mm F1.8 fully motorized on my RS5 Gimbal, and got rid of the motor skipping issue I had.

They work but because there’s no stop on them sometimes focus motors overrun the focus. But if you need make clips to create stops they work fine

I picked up the SmallRig Seamless Focus Gear Ring (66mm–68mm) and unfortunately it didn’t work well for me. The gear ring is supposed to allow smooth focus adjustments, but it keeps jumping and doesn’t provide the consistent motion needed for precise focus pulls. Cons: Gear jumps and does not provide smooth focus Unreliable for precise focus pulls Overall, disappointing performance not suitable if you need smooth, professional focus control.

Vey nice and good

Bought literally all the sizes as have various lenses and they work well. Sturdy and the teeth are good enough to use with a focus motor system on Gimbals. We have the DJI Ronin RS3.

Purchased to use instead of the Standard adjustable Gear rings as they are really ugly. These not only work great. they look like they are part of the lens not added on.

A must have for manual lenses for video and cinematography with follow focus kit.
