I bought a 1956 Zorki 4...first year of production. It was the smoothest, quietest and most precise camera you ever saw. It has been written by some the 1956 Zorki 4 was equal to any pre-war Leica. If you are fortunate enough to find a true 1956 model (most for sale today are clever to very clumsy counterfeits) and the Jupiter lens matched to it, then I'd say get it. To know the lens matches, you must get the papers with it (which sadly also may be counterfeit). When produced, each lens was individually collimated to one specific camera. Mine was in the original box with the manual (in Cyrillic) and all the papers including the lens check slip and a signed export release form. In 1956, nearly 17,000 of these were made. The world reacted, the Soviets got the message loud and clear and the next year they opened a new factory, hired lots of unskilled laborers, taught them to perform one task and produced slightly over 70,000 of them. Never again was the Zorki 4 the darling it had been in 1956. Production standards were relaxed. Never again would it be that smooth, that accurate, that quiet. There's one on eBay now which appears to be a genuine 1956 but it has some problems. All the others are counterfeit copies.
