A camera comprising a film winder rotatable to wind individual frames of a filmstrip into a take-up chamber after each frame is exposed, and a frame counter rotatable to indicate how many frames are left to be exposed, is characterized in that a locking device is movable to secure the film winder and the frame counter in place to prevent their further rotation responsive to the frame counter being rotated to indicate there are no frames left to be exposed.
