Sigma Art 135mm f/1.8 DG HSM

Make a focus gear for your lens. Start with the measurements below, check the fit on your copy, and download a ring for your own printer.

Not verified by Focus Rings. Lenses vary between versions and copies: measure yours with a tape before printing.

Choose your ring

Added hard stops are for mechanically coupled focus rings without usable end stops. They are unnecessary on lenses with built-in stops and unsuitable for focus by wire. This preset is offered for clamp and slip-on rings.

Several lenses? Every further clamp or hard-stop ring in the same order costs €6.90. Keep one outside diameter and your focus motor stays in place when you swap lenses.

Before you print

• Check the focus-ring diameter on your copy. A tape circumference must be divided by π to obtain its diameter.
• Print a free test ring first. Material, printer and shrinkage change the fit.
• Module 0.8 teeth fit standard follow focus units and focus motors from ARRI, DJI, PD Movie and Tilta.
