At least one of the interchangeable lenses is an interchangeable wide-angle lens having a distortion. The wide-angle lens has a memory for storing an exposure correction value corresponding to the distortion. The camera body includes a photometering device which measures photometering data using light transmitted through the interchangeable lenses, and a photometering data correcting device for correcting the measurements by the photometering device in accordance with the exposure correction value read from the memory when the interchangeable wide-angle lens is attached to the camera body.
