Abstract
The mounting of an interchangeable lens having a predetermined or lesser back focus and an intermediate adapter is limited by camera bodies and the intermediate adapters. A camera system has two kinds of bodies having metal backs of the same dimension and body side mounts of the same shape, a plurality of interchangeable lenses having a common lens side mount engageable with the body side mounts, and a plurality of intermediate adapters between the interchangeable lenses and the camera bodies. The first body has an escape portion in the body side mount over the mounting range of the interchangeable lenses or the intermediate adapters so that the mounting of all the interchangeable lenses and all the intermediate adapters may be possible. The second body has a flange portion in the body side mount so that the mounting of an interchangeable lens having a predetermined or greater back focus and an intermediate adapter mountable only on this interchangeable lens may be possible.
