Abstract
A photographing lens assembly is provided with a moving lens system which is movable within a given moving range to change the optical characteristics and an electrical driving apparatus for controlling the movement of the moving lens system and comprises a mechanical limiting device and an electrical limiting device. The mechanical limiting device is adapted to act on the moving lens system when this system has been moved up to the limit of the moving range in order to inhibit any further movement of the lens system beyond that limit. The electrical limiting device is adapted to act on the electric driving apparatus when the moving lens system reaches a position a determined amount before the limit of the given moving range in order to inhibit the control for further moving the lens system in the same direction by the electric driving apparatus.
