The Movikon was a series of movie cameras, the first of which was the Movicon 16. I don't have much information on it, except it was an interchangeable lens 16mm movie camera produced in the mid-1930's.
More common are the 8mm Movikon cameras made after World War II. These are of rather unusual design as the film is twisted 90 degrees. The film plane is perpendicular to where it normally would be. This gives the camera a distinctive look, the lens being located on what would be the side of a normal movie camera.
The standard Movikon 8 was usually finished in gray crinkle paint, although it can be found in brown as well. It was also available with a built in selenium light meter as the Movikon 8B.
Both of the previous models had a 10/1.9 Movitar lens. A budget version of the Movikon was sold as the Movinette. It has a single speed motor, like the earliest Movikons (the later ones have speeds of 16-48 fps) and a 10/2.8 Triotar lens.
