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.

The view-finder masks for the telephoto lenses are simple metal frames that clip to the outside of the finder, the mask for the 65 mm lens includes a negative lens.

This is an eye-level finder having three mirrors to give an upright image that is not laterally reversed, the image though is quite dark.

The image, above, shows the mirrors within the Porroflex.

A device that fits between a tripod top and the camera. The image is focused with the camera in the lower position, the camera is then raised by a rack and pinion so that the taking lens has the same position as the viewing lens.

Single exposure Attachment
The attachment comprises a back that replaces the normal camera back and single dark slides. A catch on the slide is released to push the plate forward into the film plane.

The exposure factors are displayed in the finder as the bellows are extended.
