Abstract
Abstract A photographic camera wherein photographing mode selecting circuit is provided to select a real focal length photographing mode and a pseudo focal length photographing mode for making a print of a field narrower than the field defined by the real focal length photographing mode and output means outputs a pseudo focal length signal corresponding to the pseudo focal length of a photographic lens when pseudo focal length photographing mode is selected. The camera is reset to the real focal length mode if the film is changed, the lens is changed or the main camera switch is turned off.
