Twin Lens Reflex Camera

Twin Lens Reflex Camera

The TLR camera has two objective lenses of the same focal length. One of the lenses is the photographic objective (the lens that takes the picture), while the other is used for the waist-level viewfinder system. The fixed mirror deflects the light rays coming through the lens to a top screen, which shows the image upright but laterally reversed. Light from the object also goes through the taking lens, which is mounted on a common panel with the viewing lens, and is projected on the film. (1994 Encyclopaedia Brittanica, Inc.)

Range Finder Camera

In 1913 a German design engineer, Oskar Barnack, produced a prototype 35mm camera. In 1924 the camera went into production at the Leitz factory in Germany. It was called the Leica from the initials of "LEItz CAmera".
