This gear fits the Zeiss 18mm f/3.5 Distagon ZF.2 lens.

It is designed specifically to fit this lens and is compatible with any standard 0.8 Module follow focus. The gear sits 3-6mm “high” off the focus ring of your lens for a clean, low profile gear that slides smoothly onto your lens and into your current lens case. The gears do not have to be removed after each use although you can if you like. This gear uses a specially made C shaped insert that will allow the gear to be installed without removal of the aperture ring on this lens. Each gear comes with a lifetime of support.
