The Mamiyaflex was introduced in 1957, this is a later model of 1965. The camera is unusual in being a twin-lens design with interchangeable lenses. A long bellows extension is provided giving a very close focus. It is a large and slightly cumbersome camera to use but ideal in a studio. A nice feature is the display of exposure factors above the focusing screen, these can also be used to compensate for parallax. The factors for the wide-angle lenses are on a separate removable plastic plate above the screen. A pointer moves across the factor scale as the camera is focused, a dial is set on the camera body to indicate the lens in use. When removing a lens the camera is set to 'unlock', this moves a baffle behind the lens to exclude the light and displays a pointer in the view-finder. The price was £111 without a lens.
