The Rittreck is a 6×9cm SLR without a revolving back, made from 1955 by Musashino Kōki. The most common versions are the Rittreck IIA and Rittreck SP. The Optika IIA was a name variant of the Rittreck IIA, sold by Seymour's, a distributor based in New York. The camera is a modern, metal-bodied version of the wooden-bodied SLR cameras of the early 20th century, like the Soho Reflex. It has rack-and-pinion focusing and a cloth focal-plane shutter.
The standard lens is Musashino's own 105mm f/3.5 Luminon or Luminant. A 90mm lens is the shortest that can be fitted, because of the rigid body. Advertising for the camera noted that, because lenses fit with interchangeable lens boards as in a large-format camera, the user's own lenses can be used, whether shuttered or not.
The roll film holder allows several formats (8, 1, 12 or 16 exposures on a 120 roll) by the use of removable masks.
