One of the hard things to find is the GT2 pulley, fitting GT2 belt and a way to attach them to your lens for automated focus with a stepper motor. You will not find a pulley that is easily adapted to your lens, so you'll be left with custom designs.

We make a custom pulley in-house - designed for 28mm diameter lenses to be press fitted on your lens. Created in high quality, durable PLA, it will last you a lifetime.
