Abstract
In a camera adapted to function with stored data, aperture value data is stored at a predetermined step in accordance with a manual operation of a manually operable member and digital data, showing a controllable range of an aperture diaphragm of an interchangeable lens, is transmitted from the interchangeable lens and read. The stored aperture value data is detected to determine whether such data is out of the controllable range and the aperture value data to be stored is set to a limited value within the controllable range when the detection of the stored aperture value data is out of the controllable range.
