    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.

    摘要： A camera having a real-image viewfinder incorporating an optical finder system having the functions of an optical system for automatical focusing or an optical system for automatic exposure. The optical finder system comprises an objective lens having a positive power, an eyepiece, and an optical system such as porro mirror, disposed between the objective lens and the eyepiece and comprising a plurality of mirrors and/or a prism. Some of the mirrors a semitransparent mirrors capable of dividing the incident light for two optical paths. One part of the incident light is transmitted to the eyepiece and the other part of the incident light is transmitted to light receiving elements, which are disposed in substantially conjugate planes with respect to the focal plane of the objective lens, respectively for distance measurement and light measurement.

    摘要： A camera accessory is provided which allows a camera to photograph in a pseudo focal length photographing mode. In the pseudo focal length photographing mode, a portion of an image recorded onto a film is reproduced on a print with larger enlargement than a normal image. Therefore, a print can be obtained as if it has been printed from an image recorded on a film which had been photographed by an objective lens having a focal length longer than the actual focal length of the objective lens used. Thus, according to the camera accessory, photographing in the pseudo focal length photographing mode can be possible if used in a camera which is originally incapable of the pseudo focal length photographing mode.
