Abstract
A finder optical system is shown which includes a photo-taking lens, a mirror reflecting light rays passed through the photo-taking lens upward, a focusing screen on which a first object image is formed, a relay lens system through which the first object image is reformed as a second object image smaller than the first object image, and an eye piece which enlarges second object image. The relay lens system is located above the focusing screen and parallel to an optical axis of the photo-taking lens. The finder optical system allows for compactness in both depth and height.
