Abstract
A single lens reflex camera includes a rotatable built-in flash unit. An optical member, such as a pentaprism, conducts light rays to an eyepiece unit. Pentaprism has a right roof surface, a left roof surface, and a third reflecting surface. Third reflecting surface enables light reflected by the roof surfaces to pass to the eyepiece unit. The built-in flash unit is rotatable between a housed position, in which a light emitting unit is housed within a camera body, and a use position, in which the light emitting unit projects from the camera body. The built-in flash unit rotates centered on a rotation axis that is parallel to a photographic optical axis, extending from the camera to a photographic object. When in the housed position, the light emitting unit is positioned along either the left or right surface of surface of the optical member.
