ABSTRACT:
An improved bayonet mount is employed to removably mount a lens on the body of a camera. The body has an opening adapted to receive axial insertion of a marginal portion of the lens. A plurality of circumferentially-spaced slots extend radially into said body from said opening. A corresponding plurality of similarly-spaced claws are mounted on the lens marginal portion. The claws and slots are cooperatively configured so as to permit the lens marginal portion to be axially inserted into the opening only when the lens is angularly aligned relative to the body opening, and to prevent any claw from entering the wrong slot in the event that the angular alignment is incorrect.
