ABSTRACT:
A photographing device includes a photographing optical system and a viewfinder optical system provided independently of the photographing optical system, and at least one lens which constitutes the viewfinder optical system and has respective lengths extending in opposite directions from an optical axis of the lens to a periphery thereof, the respective lengths being different from each other in a horizontal direction and/or vertical direction. In the photographing device, the lens which constitutes the viewfinder optical system may be arranged in such a manner that a length extending toward the photographing optical system from an optical axis of the viewfinder optical system to the periphery of the lens is longer than a length extending in a direction opposite to the photographing optical system from the optical axis to the periphery. Such a photographing device enables observation (confirmation) of an entire object to be photographed, even during close-distance photography.
