PROBLEM TO BE SOLVED: To provide an exchange lens for improving detection precision of brightness information of an object, and to provide a camera body and a camera system. SOLUTION: In the camera system allowing the exchange camera 1 having a photographing system 11 to attach and detach to and from the camera body 2, the exchange lens includes stereoscopic angle information concerning the axial outside of the photographing system, and a lens information storing means for storing spectral transmittance information of the photographing system. The camera body includes a light receiving means 19 for receiving a light flux passing the photographing system, and a correcting means for correcting shift between brightness distribution of an object by using information from a lens information means and brightness distribution of an object image on the basis of a signal obtained in the light receiving means.
