Abstract
A digital single lens reflex camera includes a reflector located in a photographic light path to reflect object-carrying light transmitted through a photographic optical system toward a finder optical system. An image pickup device is located at the imaging plane of the photographic optical system. The object-carrying light in the photographic light path is reflected by the reflector in a direction substantially away from an eyepiece optical system of the finder optical system. A reflection light path is formed in the vicinity of the photographic optical system and is provided with a plurality of reflection surfaces to make the light reflected by the reflector in the photographic light path incident on the eyepiece optical system. Furthermore, a relay optical system is located in the reflection light path to relay an image formed on a primary imaging plane, which is optically equivalent to an image pickup surface of the image pickup device, to the eyepiece optical system.
