ABSTRACT:
A miniature single lens reflex camera using cassette film is disclosed. The camera can be operated with inexpensive lenses not having large back focus, due to the addition of a glass block between the shutter and the film plane. The finder optical system is short in actual length due to the combination of a trapezoidal prism, a right angle prism, and an equilateral prism.
