A camera comprising a film winder rotatable in engagement with a film spool inside a cartridge to wind an exposed filmstrip into the cartridge, a frame counter rotatable to indicate the number of exposures remaining for picture-taking and having a circular array of teeth that are successively engaged to rotate the frame counter, a metering sprocket engaged intermittently with successive perforations in the filmstrip to rotate the metering sprocket as the filmstrip is wound into the cartridge, an actuator coaxially connected to the metering sprocket for rotation in engagement with the respective teeth to rotate the frame counter, and a disabling mechanism for preventing rotation of the frame counter after the last exposure is made and keeping the metering sprocket disengaged from anyone of the film perforations to permit rotation of the film winder to complete film winding into the cartridge without rotating the frame counter and the metering sprocket, is characterized in that the disabling mechanism is coaxially connected to the actuator for engaging the frame counter when the metering sprocket is disengaged from the film perforations, to prevent rotation of the frame counter and the metering sprocket as the film winder is rotated to complete film winding into the cartridge.
