The Ukrainian Kiev 35mm rangefinder cameras are not "technically" copies of the Contax cameras, as the whole production line and technicians making the pre-WW2 Contax cameras was moved from occupied East Germany to Kiev after the war and production was resumed, and thru the lifespan of this line of cameras, certain things were changed, but in actuality the Kiev 35mm rangefinder cameras were an extension of the original pre-WW2 Contax rangefinder cameras. The Post-WW2 Contax rangefinder cameras made in Germany were completely redesigned, but have some superficial resemblence, and accept the same lensmount as the pre-WW2 Contax rangefinder cameras.
