发明名称 Finder optical system and camera having finder optical system
摘要 A camera including a photographing optical system and a finder optical system, includes an objective optical system and an ocular optical system, the optical axes thereof being parallel with each other; a reflection surface which reflects a light bundle in the vertical direction of the camera; a reflection surface which reflects the light bundle in the horizontal direction of the camera toward an light-emitting optical axis of the ocular optical system; and a reflection surface located on the light-emitting optical axis to make a connecting optical axis coincident with the light-emitting optical axis of the ocular optical system. The connecting optical axis is inclined with respect to the horizontal direction of the camera so that the optical axes of the objective optical system and the ocular optical system are close to each other with respect to the vertical direction of the camera.
