摘要： A camera in which a supertelephotographic lens system and a standard photographic lens system are arranged within a camera body and a standard viewfinder system and a supertelephotographic viewfinder system are so arranged that an operator can view an image of a subject through the same eyepiece window in either the standard or supertelephotographic mode. In addition, a control means is provided for controlling the use of a built-in electronic flash depending upon the selected mode and more particularly for inhibiting the use of the flash in the case of the supertelephotographic mode.

摘要： A camera which has a macro-photographic optical system for taking the magnified picture of a minute object or specimen, a first viewfinder system for permitting to view the magnified image of the object or specimen in the case of macro-photography, an illumination source for illuminating the object or specimen in the case of macro-photography, a normal or standard photographic optical system for taking the standard picture of a subject or object, a second viewfinder system such as an inverted Galilean finder used in the case of standard photography and an electronic flash. The selection of the macro-photographic mode or the standard photographic mode can be accomplished only by shifting a single optical element; that is, a reflecting mirror mounted in a mirror box.The camera has such a superior feature that the camera is very simple in construction yet capable of highly effective results in practice while in the case of macro-photography, a specimen can be clearly viewed and sharply focused.

摘要： A photographic lens device with a built-in electronic aperture-stop control system or mechanism comprising a step motor and an aperture-stop setting device which are spaced apart from each other by a suitable distance in the direction of the optical axis of the photographic lens system and are coupled to each other through a coupling means. In one embodiment, the aperture-stop control system can be incorporated in the lens device simply by slightly enlarging the diameter of the lens device or barrel without increasing its axial length because of full possible use of a heretofore unused dead space available in the lens device.

摘要： A focus state indicator for a camera is provided such that the photographer may know a focus state in accordance with electrical signals respectively corresponding to the lens position in the previous focusing operation and a distance between a camera and a subject to be photographed. A circuit is arranged to generate a differential signal between the output electrical signals. The alarm operation of an alarm element is continuously changed between focused and out of focused states in accordance with the differential signal, so that the photographer can know the focus state.

摘要： Image focusing device especially adapted for use in single-lens reflex cameras. A light-beam emission or projection means is incorporated in each interchangeable photographic lens in such a way that the direction of the light beam emitted or projected therefrom can be varied in response to the axial displacement of a lens group for focusing an object. The light rays which are reflected from the object and pass through the photographic lens along and in the vicinity of its optical axis are intercepted by a photodetection means disposed within a camera body, whereby whether or not the photographic lens is sharply focused at the object can be detected.
