A lens-fitted photographic film unit is pre-loaded with photographic film. First and second stationary openings are formed respectively in front of first and second exposure chambers. A wide-angle taking lens is disposed in front of the first stationary opening, and has a shorter focal length. A telephoto taking lens is disposed in front of the second stationary opening, and has a longer focal length. In response to operation of a shutter release button, a single shutter plate slides horizontally. Wide-angle and telephoto movable openings are formed in the shutter plate and are registrable with the respective stationary openings. The telephoto movable opening is different in size from the wide-angle movable opening. When the shutter plate is slid, the movable openings open or close the stationary openings simultaneously, and expose the film to make two simultaneous exposures. In a preferred embodiment, the wide-angle lens is disposed behind the shutter plate. A transparent lens plate is disposed in front of the shutter plate to cover the shutter plate, and is provided with the telephoto lens.
