This gear fits the Asahi Opt. Co. Super-Multi-Coated Takumar 17mm f/4 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. Each gear comes with a lifetime of support.
