Abstract
An indicator within a finder of a single lens reflex camera is provided with a simple construction. The indicator may include a mirror for reflecting light of an object transmitted through a photographing lens to form an object image onto a focusing plate, an finder optical system for viewing an image of the object formed on the focusing plate, a hollow-type pentagonal mirror, and a photographing information projector for projecting a plurality of light rays onto the focusing plate to form a photographing information image. The hollow type pentagonal mirror may include a pair of roof reflecting surfaces and a third reflecting surface for reflecting light, reflected by the pair of roof reflecting surfaces, toward an eyepiece optical system. The photographing information projector may be mounted in the vicinity of the pair of roof reflecting surfaces.
