ABSTRACT:
A lens-fitted photographic film unit has telephotographic and wide angle lenses to perform telephotography and wide-angle photography simultaneously, and a viewfinder to observe the taking field at least for telephotography. A telephotographic lens is arranged in front of a single shutter blade, behind which a wide-angle lens is arranged. The telephotographic lens is disposed on the side of a film supply chamber while the wide angle lens is disposed on the side of a film take-up chamber. The viewfinder is disposed directly over the telephotographic lens to compensate parallax. The front window of the viewfinder is provided with a translucent film whose middle portion is clear. The entire frame formed by the front window is the visual field frame for standard photography and the frame formed by the clear portion is the visual field frame for telephotography.
