Abstract
A photographing lens includes an eccentricity adjusting frame which holds an eccentricity adjusting lens group serving as a part of a photographing optical system of the photographing lens; a lens support frame, an axis of which is coincident with a predetermined optical axis of the photographing optical system, supporting the eccentricity adjusting frame in a manner to allow the eccentricity adjusting frame to move in a plane orthogonal to the predetermined optical axis during an assembly-stage of the photographing lens; and a fixed aperture member having a circular aperture, the fixed aperture member being integrally formed with the lens support frame so that a center of the circular aperture coincides with the axis of the lens support frame.

A photographing lens comprising:
- an eccentricity adjusting frame which holds an eccentricity adjusting lens group serving as a part of a photographing optical system of said photographing lens;
- a lens support frame, an axis of which is coincident with a predetermined optical axis of said photographing optical system, supporting said eccentricity adjusting frame in a manner to allow said eccentricity adjusting frame to move in a plane orthogonal to said predetermined optical axis during an assembly-stage of the photographing lens;
- and
- a fixed aperture member having a circular aperture, said fixed aperture member being integrally formed with said lens support frame so that a center of said circular aperture coincides with said axis of said lens support frame.
A photographing lens comprising:
- a lens holder which holds a frontmost lens group of a photographing optical system;
- a lens-holder support frame which supports said lens holder in a manner to allow said lens holder to move in a plane orthogonal to an optical axis of said photographing optical system during an assembly-stage of the photographing lens, said lens holder and said lens-holder support frame being concentrically arranged;
- and
- a fixed aperture member having a circular aperture, said fixed aperture member being integrally formed with said lens-holder support frame so that a center of said circular aperture coincides with an axis of said lens-holder support frame.
