This 1950’s Mamiya Super 16mm sub-miniature spy camera, was designed for 16mm film with an image size of 10 x 14mm. The lens is a 25mm f/3.5 with aperture adjustable to f/11. A built-in yellow filter can be slid in front of the lens. The viewfinder slides out, and states a range of 1 ft to infinity. The shutter is synchronized for a flash (not included) and is adjustable from .5 to 1/200 sec, plus a bulb.
All functions appear to be in good working order, although the camera has not been tested with actual film. A film take-up spool is included. And the original leather case is in good condition and is included.
