Tilta Seamless Focus Gear Ring 75-77mm TA-FGR-7577

Tilta Seamless Focus Gear Ring for 75mm to 77mm Lenses

The Tilta Seamless Focus Gear Ring (model TA-FGR-7577) is designed to add 0.8 MOD gears to compatible lenses with an outer diameter between 75mm and 77mm, enabling use with cine follow focus systems. This gear ring fits virtually all lenses within this diameter range, providing a versatile solution for professional cinematography.

Design and Construction

This seamless gear ring is an improved version over previous Tilta gear rings. It features a fully closed design that requires no screws for attachment, allowing for easier installation and removal. The ring applies evenly distributed pressure around the lens barrel, ensuring zero drifting and maintaining accurate focus control during operation.

Constructed from durable and flexible rubber, the gear ring attaches firmly to the lens and operates silently and smoothly through a full 360° rotation. The MOD rating (0.8) and the diameter size (75-77mm) are etched on the inside of the ring for easy identification.

Tilta offers 14 different sizes of seamless focus gear rings to accommodate a wide range of lenses. The 75-77mm size is compatible with many popular lenses from Sony, Canon, Panasonic/Olympus, Nikon, FUJIFILM, Sigma, Tokina, and ZEISS. Below are examples of compatible lenses confirmed by Tilta:
