ABSTRACT:
A lens holding structure is incorporated in an optical system, such as the photographing optical system of a camera. The lens holding structure has a holding member (i.e., a lens frame) for holding a non-circular lens included among the lenses of the photographing optical system. The non-circular lens has an arcuate outline portion and a linear portion. The holding member holds the non-circular lens by supporting it at at least three points on the arcuate outline portion without touching the linear portion of the lens. The lens holding structure is simple and enables easy and accurate assembly of the optical system of the camera.
