Tilta Seamless Focus Gear Ring (81 to 83mm)
Key Features
  • 0.8 MOD Gear for Cine Follow Focuses
  • 81 to 83mm Diameter for Focus/Zoom
  • Fully Closed and Requires No Screws
  • Even Pressure, No Drifting, Accurate
Tilta's 81 to 83mm Seamless Focus Gear Ring allows you to add 0.8 MOD gears to a compatible lens for use with cine follow focuses. This 81 to 83mm size fits virtually all lenses of the same outer diameter. 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 it works silently and smoothly along 360° of rotation. The MOD rating and 81 to 83mm diameter size are etched out on the inside of the ring.

My follow focus keep slipping because the teeth aren’t hard enough but for 2 bucks can’t beat it

Perfect fit for Panasonic

By David
Rated 5 out of 5
Date: 2022-12-21

Purchased this to use with my Panasonic Lumix S PRO 16-35mm f/4 and a SmallRig Mini Follow Focus 3010B. It was a tad snug going over the front of the lens, but fits the focus ring perfectly. Can't beat this for the price!

Any experiences with the Sigma 18-35 and Sigma 50-100? Which size would be best?
Asked by: Daniel
The Sigma 18-35mm Art lens has a 78mm diameter, you would need BH #TITAFGR788 instead. While the 50-100mm has a 93.5mm diameter and you would need a universal gear like BH #WILU for that one. https://bhpho.to/3kOCoMI https://bhpho.to/309Ib7v

Asked by: Micah
No, the Tilta Seamless Focus Gear Ring seamless rings are not compatible with the DJI Focus motors. seamless rings may not have long enough teeth for the motor to grip. We recommend using the following gears. DJI Ronin-S Focus Gear Strips (2-Pack) BH #DJGEARP19 • MFR #CP.RN.00000026.01

Which size will fit the Canon 24-70 f/2.8 mark II focus ring?
Asked by: Michel
The 81-83mm will fit the focus ring. Go a size down at your own risk. So far the 81-83mm fits great and allows me to use my follow focus system. I leave the ring on at all times as well. Doesn't obstruct the reversal of the hood either.

Asked by: Braulio
The Tilta Seamless Focus Gear Ring (81 to 83mm) would not fit on the Tamron 35-150mm f/2-2.8 Di III VXD Lens (Sony E) as it has a diameter of around 89mm. It would be recommended to measure the size of the control ring that you would like to mount the gear ring on in order to get the best fit.

We have found the Canon EF 24-70mm f/2.8L II USM Lens to have an 82mm diameter for its focus ring. As such, the Tilta Seamless Focus Gear Ring (81 to 83mm) should work great for it.
