Zorki-4 is a 35 mm rangefinder camera, manufactured by Krasnogorsky Mekhanichesky Zavod (KMZ) , (Красногорский механический завод = Mechanical Factory of Krasnogorsk), near Moscow, former USSR and produced between 1956-73, quantity 1715677. ЗОРКИЙ = Zorkiy, means Sharp Sight. Zorki-4 was possibly the most popular of all Zorki cameras. The Zorki-4 was also the first of the Zorki cameras to be exported in large numbers to the west.

When the Zorki-4 rangefinder was introduced in 1956, its contemporaries included the Zorki S, Zorki 2S, FED 2b, Leica M3 (introduced two years before), Leica IIIg, Nikon S2, Canon VT, Canon L1. The Zorki 4's production run outlasted all of them. When it morphed into the Zorki-4K by 1973, its contemporaries included the FED 4b, Leica M4 and M5, Nikon F2, and Canon F-1 and Canon Canonet QL 17 GIII.

The Zorki-4 is basically a Zorki-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 - 1s, 1/5, 1/10, 1/25, 1/50, 1/100, 1/250, 1/500, 1/1000 +B - and strap lugs. Later bodies (post ~1965) have fabric covering and the more modern base 2 logarithmic shutter speed progression: 1s, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000 and the figures are silk-screened. By the mid-sixties, the strap lugs had disappeared.

There are at least 32 types/versions of the Zorki-4 [1] [2] [3] [4] or as to Aidas Pikiotas there are 4 versions and 13 types[5]
