ABSTRACT:
A finder for single-lens reflex type digital cameras includes a reflecting plane for splitting a light beam from an imaging optical system of a camera into two beams directed toward an image sensor and a finder system, a prism system for erecting an image, and an ocular optical system. The prism system has an entrance surface, a reflecting surface consisting of one plane, a reflecting surface of roof shape, and an exit surface. An optical path between the entrance surface and the reflecting surface consisting of one plane is practically perpendicular to an optical path between the reflecting surface of roof shape and the exit surface in the prism block.
