Method and apparatus for identifying interchangeable lenses

Abstract

A description is given of a method for identifying interchangeable lenses (1) that can be connected with the aid of a locking apparatus (2) in a prescribed position to a support surface (9) on a camera of a camera system, wherein after the locking operation is performed a defined optical radiation is directed from two or more, preferably six light transmitters (18) arranged in the support surface (9) to reflecting or absorbing surfaces (8) on the locking apparatus (2) which are assigned to said light transmitters, the radiation returning from the respective reflecting/absorbing surfaces (8) is picked up by light receivers (19) arranged next to the light transmitters (18) in the support surface (9) and a binary coded signal for identifying the interchangeable lens (1) is formed from the output signals of the light receivers (19). Also described is an apparatus for carrying out the method.
