ABSTRACT:
A photographic camera has an interchangeable lens assembly with a lens mount and a camera body with a body mount engageable with the lens mount, a source of binary signals with at least two bits representative of the minimum aperture value in the lens assembly, and a mechanism in the camera body for receiving the binary information. A rear aperture converter has a first mount engageable with the lens mount and a second mount engageable with the body mount. One bit of the binary information is transmitted from the first mount to the second mount without change. The other bit of the binary information is transmitted from the first mount to the second mount in inverted form.
