A single lens reflex camera has a finder optical system that observes an image formed on a reticle by an objective lens, and a photometric device that measures light transmitted through the reticle via at least a part of the finder optical system, at a position shifted from an optical axis of the finder optical system. The finder optical system comprises a Fresnel lens surface which transmits light from the objective lens, and the Fresnel lens surface is positioned so that the center of the Fresnel lens surface is shifted in a direction to cross the optical axis of the finder optical system according to a position of the photometric device.
