  • Patent number: 5353077
    Abstract: A photographic camera having also a function of panoramic photographing includes a panorama switch which is turned ON to change over the mode of photographing to the mode of panoramic photographing and to activate a drive motor to forcibly move an objective along the optical axis to the minimum focal distance position. A slidably movable knob member serving for switching of the photographing mode is provided laterally of a viewfinder, and a photographing mode display appears on the external surface of the camera as the knob is slidably moved to select the mode of panoramic photographing.
