Abstract
A photographic apparatus, particularly a still camera, wherein two lenses having different focal lengths are pivotable about the axes of two shafts which are located diametrically opposite each other with respect to the axis of a third shaft which supports a two-armed lever. The mounts of the lenses are coupled to the adjacent arms of the lever by pin-and-slot connections, and the lever is pivotable by a reciprocable knob to move one of the lenses into register with the light-admitting aperture when the knob is moved in one direction and to move the other lens into register with the aperture when the knob is moved in the opposite direction. The lenses are installed in the camera body at the opposite sides of the aperture, and the body has stops which arrest the respective lenses in operative positions. The lever has cams which cooperate with a leaf spring to yieldably hold either of the two lenses in register with the aperture. The shafts for the lenses and the respective lenses are adjustable axially in parallelism with the optical axes of such lenses.
