ABSTRACT:
A zoom lens camera enables an object to be photographed at a desired focal length. The camera is operated to set a focal length in a memory. The zoom lens is then driven to the setting that is stored in the memory. The focal length of the zoom lens is detected; and the driving of the zoom lens is controlled in accordance with the result of a comparison made between the value that is stored in the memory and the detected focal length of the zoom lens.
