A lens-fitted photo film unit is pre-loaded with photo film, and includes a viewfinder adapted for observing an object. A selector button is operable externally, for being shifted to a standard position and a telephoto position. A view region changer lever sets the viewfinder in a standard view field when the selector button is in the standard position, and sets the viewfinder in a telephoto view field when the selector button is in the telephoto position, the telephoto view field being included in the standard view field. An information exposure unit photographically records a telephoto discernment PAR code to an information exposure region in the photo film when the selector button is in the telephoto position. The telephoto discernment PAR code includes at least three dots, for designating production of a pseudo telephoto print from a region in an imaging frame in the photo film corresponding to the telephoto view field.
