Zorki 4
When the Zorki 4 was introduced in 1956, its contemporaries were, among others, the Zorki S, Zorki 2S, FED 2b, the two-year-old Leica M3, Leica IIIg, Nikon S2, Canon V-T, Canon L-1. The Zorki-4's production life outlasted all of them. When it morphed into the Zorki 4K by 1973, its contemporaries were, among others, the FED 4b, Leica's M4 and M5, Nikon F2, and Canon's F1 and Canonet GIII-17.
The Zorki-4 is basically a 3S with a self-timer. It retained all of the features and strong points of the 3S. The early bodies have vulcanite body covering, engraved shutter speeds, and strap lugs. Later bodies have fabric covering and the shutter speeds (1/60 and 1/30 instead of 1/50 and 1/25) are silk-screened. By mid-sixties, the strap lugs had disappeared.
