ABSTRACT:
A portrait photograph camera incorporates a taking lens assembly having a predetermined focal length, and photographs a human head on instant film. A pair of indicia are displayed within a field frame of a viewfinder. According to the indicia, the human head is framed or targeted. The framed human head is photographed, so as to create an image having a predetermined size range on the film. In a preferred embodiment, a telephoto converter lens is selectively mountable on the taking lens. Combined with the telephoto converter, the taking lens has a longer focal length. A second pair of indicia are displayed within the finder field frame. The human head as framed by the second indicia is photographed at the longer focal length so as to create on the film an image in the former predetermined size range. A rangefinding device measures the subject distance. When the subject distance is too great for photography through the taking lens without a converter lens, a telephoto indicator lamp displays in the viewfinder an instruction to mount the telephoto converter lens on the taking lens assembly. Another converter lens, with its associated indicia, is provided to shorten the focal length for wide-angle photography.
