The very unusual Biflex 35 was manufactured by E. Schmid, Feinmechanische Konstructions - Werkstatte, Urdorf, Switzerland between 1948 (1950?) and 1953. It creates 11x11 mm exposures in staggered vertical pairs on 35mm roll film to give 200 slides. The film was fed through from a reversible cassette made by Biflex to another similar cassette. At the end of the film the cassettes were taken out, turned over re-inserted. The film counter is marked from 1 to 100.

The lens is a Meyer Gorlitz Trioplan f2.8 20mm or a Biflex Trivar f2.8/20mm is mounted in the middle of the body with aperture and shutter speed sets below and to the right of the lens. Shutter speed of 1/10 , 1/25, 1/50, 1/100 and 1/250. The camera is 3 3/4 x 2 7/16 x 1 7/16 inches and weighs nearly 1 lbs. With a heavy body all the markings are heavily stamped into the metal. Numbers up to 1249 have been seen but less than 500 may have been made.

The view finder is tiny with a 1/16" diameter round sight.

The shutter release is very smooth and perhaps the best mechanical shutter on any subminiature camera.

Accessories included a nickel lens cap, a lighted format punch for making up transparencies in special holders, a large and heavy slide projector and two projection lenses f1.6 50mm and f1.6 35mm all fitting into a large covered wooden box.

Sold in and around Zurich some were exported to the United Kingdom.

A second model called the Duoflex was planned and registered as a design and trademark. A prototype may have been built, but there was no production.
