18x zoom lens with 3-CAM Motor Drive. Triple support and guidance of the zoom and focus ensures a very smooth, silent and reliable operation.
In order to use pre-set positions with zoom lenses, the lens has to have pre-set potentiometers built in which sends a feedback voltage to the control equipment. This allows the lens to return to a pre determined position pre-determined by the control equipment
When using motorized zoom lenses it is always necessary to back focus the camera in order for the lens to be
able to properly track focus.
