Find the gear
for your lens.

Sony mirrorless cameras are everywhere in run-and-gun video, and most Sony lenses use a focus-by-wire ring that has no hard stop. A gear on the ring still gives you a repeatable grip for a follow focus or motor, and many shooters add one to their G Master and FE zooms for gimbal work. We list gears for about forty Sony lenses, including Zeiss-branded ZA models for E-mount.

Typical ring sizes

The FE 24-70mm f/2.8 GM uses 3.07–3.15 in (78–80 mm) on the focus ring and 2.95–3.03 in (75–77 mm) on the zoom ring. The FE 70-200mm f/4 G OSS is 3.07–3.15 in (78–80 mm) on both rings. Primes are smaller: the FE 85mm f/1.8 needs 2.95–3.03 in (75–77 mm), and the FE 35mm f/1.8 sits at 2.48–2.56 in (63–65 mm).

Good to know

• Focus-by-wire rings have no mechanical stop, so calibrate your follow focus or motor once after fitting.
• Power zoom lenses such as the E PZ 18-110mm f/4 G OSS have a dedicated zoom lever, so check whether a gear is listed for your model.
• If your lens is not here, the gear for any lens covers 2.24 to 3.62 in (57 to 92 mm).
