The KC2-E is a control unit for operating remotely controllable lenses. The controls for zoom, focus and aperture are designed as bidirectional buttons with a neutral center position. For the three functions mentioned above, the adjustment speed can be adjusted by means of a rotary control. By changing the polarity (actuating the rocker switches), for example, the aperture is opened or closed. In addition, the device can swivel the internal focal length extender in and out of the zoom lens.
