    摘要: 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.

    摘要: A camera having, in addition to a real focal length photographing mode, a pseudo focal length photographing mode, namely, a photographing mode in which a part of a photographed image frame of a film is printed at an enlarging ratio different from an ordinary enlarging ratio to obtain a print as if it had been photographed using a telephoto lens. It is provided with means for recording photographing mode information on a frame of a film when the pseudo focal length photographing mode is selected, and a control means which brings a flash light emitting device into an operable condition in response to the selection of the pseudo focal length photographing mode and which actuates the flash light emitting device in synchronism with release of the shutter. An optical axis of a photographing lens and a flash emission tube are spaced from each other, and the pseudo focal length photographing mode can be selected only when a negative film is loaded in the camera.
