The CINEGEARS Single-Axis Extreme Motor provides precise repeatable control of your focus, zoom, or iris ring, and it provides twice the torque as the Single-Axis motor and is suitable for use with prime lenses and even stiff zooms. It is compatible with an optional CINEGEARS controller, Single, Multi, Rocker, or Espresso, and ships with an interchangeable cine-style 0.8 MOD drive gear. It requires an optional power cable and rod clamp, which are available separately. You may use this motor to drive the focus, zoom, or iris gear ring on your lens. Once mounted, the lens motor will calibrate itself to your lens in a simple process. You can also manually remap your lens with the optional hand controller, and program multiple stops along the lens, simulating either hard stops, or focus positions. The motor direction is electronically reversible if you need to change the orientation of your motor, or are working with a lens that focuses in the opposite direction to standard cine lenses. The motor incorporates a LEMO jack for power and a LANC jack for camera start / stop.
