Ginrei Vesta cameras

(1950) The Vesta is one of the early Hit-type cameras -- or should I say "two of the early Hit-type cameras"? There were two models and they appeared shortly after the end of the War. The basic features were the same on both versions. They had a fixed-focus, 20mm (f4.5) lens, which is quite "fast" for a 17.5mm camera. They had the typical shutter speeds of B and 1/25. The difference between the two models? One had a plain viewfinder while the other had a dual viewing system. It has a normal eye-level viewfinder but a waist-level finder has been added to the top, as well. This can function as a spy-finder in a pinch. It is not known if these two models were produced at the same time.
