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.
