Abstract: A photographic camera in which a manually operable shutter tensioning member normally serves, through gearing, to advance the film simultaneously with tensioning or cocking the shutter. A manually operable control member has three positions. In its central position, the gearing meshes in normal operative condition so that the movement of the shutter tensioning member drives both the film metering sprocket and the film take-up spool, so as to feed the film ready for the next exposure. In one extreme position of the control member, the gearing is disconnected so that the shutter tensioning member can be moved to tension the shutter without driving either the film measuring sprocket or the film take-up spool, and at the same time the part of the gearing connected to the take-up spool is frictonally locked to prevent accidental undesired movement of the take-up spool.
