ABSTRACT:
A lens-fitted photographic film unit is pre-loaded with unexposed photographic film, which is contained in a main body of the unit. A rear cover is secured to the main body to cover the rear of the film. An exposure aperture is formed in the main body in front of the film, and exposes the film so as to create an imaging frame, in a wide-vision aspect ratio in which a 35 mm full size is narrowed down widthwise. A single taking lens element focuses an image on the film, and has a focal length from 25 mm to 35 mm, a transverse chromatic aberration of at most 65 .mu., and a distortion of at most 0.9%. The aspect ratio of the imaging frame is 16/9. At least one train of ridges is formed on longer sides of the exposure aperture and is adapted to form marginal images outside the imaging frame by casting patterned shadows on the film.
