Abstract: A still camera or motion picture camera wherein the shutter and/or the diaphragm is adjustable in response to rotation of a ring which is installed in a circumferential groove of the lens mount. The picture taking objective is movable in the direction of the optical axis by a ring-shaped, lever-shaped or rotary knob-shaped adjusting device which is mounted on the ring for movement about a second axis which is inclined with reference to the optical axis and intersects or crosses in space with the optical axis. The adjusting device also serves to rotate the ring about the optical axis. The axial position of the objective can be changed independently of or simultaneously with angular movement of the ring, depending upon whether the adjusting device is actuated to merely rotate the ring, to merely move the objective axially or to move the objective axially while rotating the ring about the optical axis.
