CA 2262190

A control system for an objective of the camera, in particular a film camera, includes one or several drive units for automatically positioning at least one lens ring, e.g., for adjusting the focus position, the opening of the iris diaphragm and/or the focal length. The drive units can be used to adjust the lens ring(s) to a predefined set position. A device coupled to each of the lens rings determines the actual position of the lens rings relative to the objective and converts this position into a measuring output signal.
