摘要： A photographic camera having a real focal length photographing mode and two kinds of a first and a second pseudo focal length photographing modes. In the first pseudo focal length photographing mode, the photographic camera is capable of specifying a scope for printing narrower than the scope in the real focal length photographing mode. The photographic camera has a function for selecting either of the real focal length photographing mode and the first and second pseudo focal length photographing modes in order to output a mode signal in accordance with the selected mode, a function for measuring a brightness of an object to output a signal of the measured light in accordance with it, a function for outputting a signal in accordance with a film sensitivity and a function for calculating an exposure value in accordance with the signals of the mode, measured light and film sensitivity and also for rectifying the aperture to the open side in the second pseudo focal length photographing mode rather than in the first pseudo focal length photographing mode.

摘要： A photographing lens device wherein the optical axes of lenses can be aligned with a high degree of accuracy with a simple structure and at least a lens made of a plastic material can be secured to a lens barrel without causing a torsion thereof. The photographing lens device comprises first, second and third lenses arranged in this order from the object side. The second and third lenses have mutually contacting flat faces formed thereon outside effective light path regions therein, and the third lens is secured to the second lens at the flat faces of them by a bonding agent. The optical axis of the second and third lenses are aligned with each other by slipping the lenses along the flat faces thereof before adhesion. The second lens further has a contacting face formed outwardly of the flat face thereof and is pressed at the contacting face thereof against a face of a lens barrel while the first lens is pressed against the second lens by a pressing member coupled to the lens barrel.
