The first AF correction data is determined by the optical characteristic of the interchangeable lens and associated with the type of the light source illuminating the object of photography. The second AF correction data is determined by the optical characteristic of a system composed of the interchangeable lens and the intermediate adapter and associated with the type of the light source illuminating the object of photography.
