Rolleiflex Twin Reflex Camera

The Rollei was created in 1929. It was a twin reflex camera. A twin reflex camera is a type of camera with two lenses of the same focal length. One is used as the lens that takes the picture and the other is used for the waist-level viewfinder system. The viewfinder uses a 45-degree mirror, a matte focusing screen and a pop-up hood. The viewfinder matches the image size on film.
