ABSTRACT:
Accessories for use in photographic camera systems provide various data that are inherent to the objective lens being used and are transmitted from the objective lens to the camera body, and the various data are processed and the resultant data are used for automatic exposure control, automatic focusing, and various warnings and indications. Such data may include the maximum and minimum F-numbers, the focal length and the shortest photographable distance of the lens, data indicative of the relationship between the direction of the rotation of a motor within the camera body for automatic focusing and the direction of movement of the lens system, and data indicative of the relationship between the amount of rotation of the motor and the amount of the shifting of the image plane.
