The Belmira was an astounding camera, as astounding as the viewfinder cameras of the Belca-Werk in East-Germany. It had a big viewfinder with superimposed rangefinder, and the rangefinder had an impressive measurement base of 8 centimetres! The rangefinder was coupled to the lense's focusing ring and, for parallax correction, to the viewfinder. The lens was a typical 2.8/50mm Tessar, the shutter a Vebor with speeds from 1 sec. upto 1/250 sec. . The shutter had to be cocked before each shot.
