ABSTRACT:
A photographic interchangeable lens assembly which includes a diaphragm mechanism is provided with an aperture value transmitting member and a diaphragm actuating lever which extend axially from the lens assembly to the camera and which are moved relative to the camera when the lens assembly is attached with the camera. In order to enable these elements to be appropriately located relative to corresponding operating elements in the camera, at least one of the elements, and preferably the diaphragm actuating lever, is formed with a mechanism enabling axial contraction thereof so that a desired relative positioning, or exchange of relative locations, may be effected between the transmitting member in the lens assembly and the corresponding actuating member in the camera body when the lens assembly is mounted in operative position.
