The is a seamless lens gear for the Voigtlander Nokton 25mm f/0.95 Lens. It is compatible with any follow focus that uses a 32-pitch (.8mod) gear. This ring is continuous (no gaps or breaks) and retains the correct involute tooth form, something an adjustable gear can't do.
The gear is easy to install, it simply presses on, and won't slip, thanks to a whole lotta internal fingers that grip the focus ring. No screws or zip-ties required. Available in black or white.
