摘要： A prism optical system provided with: a first prism on which a light ray coming from an objective lens is incident; a second prism on which the light ray coming from this first prism is incident, and from which this incident light ray is emitted; and a plate-like member which is interposed between the aforesaid prisms so as to provide a predetermined air space therebetween and which has a diaphragm opening and a light blocking portion. Further, an uneven portion, which consists of depressions and projections and has a serrate section, for preventing light rays, which have been reflected from the surface of the light blocking portion of this plate-like member, from entering a field stop is provided in the light blocking portion thereof. Thereby, occurrences of ghosts and flares due to stray light are prevented. Moreover, ghosts and flares are reduced.

摘要： A real image type finder optical system includes an objective lens group having positive refracting power and an eyepiece lens group having a positive refracting power. The objective lens group includes a first group consisting of a negative lens, a second group consisting of a positive lens, a third group consisting of a positive lens and a fourth group having a negative refracting power and forming part of an image inverting optical system. Upon zooming from a wide-angle end to a telephoto end, the first and fourth groups remain fixed and the second and third groups move. The eyepiece lens group comprises a fifth group that forms part of the image inverting optical system and a sixth group having positive refracting power. The resulting real image type finder optical system satisfies specific conditions with respect to the back focus of the first to third groups at the wide-angle end.
