The Kiev II, is a copy of the prewar Contax II and the Kiev III was a copy of the Contax III, easily recognizable because of the light meter perched on top of the body. Neither of these cameras was synchronized for flash, although many were later modified. The Kiev IIa and IIIa solved this problem.
Further refinements resulted in the Kiev 4 and 4A (metered and non metered) models, which were produced from the 1950s until the 1980s with several variations and modifications. The last variants, the Kiev 4AM and 4M, had such modern conveniences as a hot shoe and real rewind crank.
There was a short-lived Kiev 5 model that was only produced from 1968 to 1973 and was incompatible with earlier Kiev/Contax lenses. It offered a large and bright finder, with frameline for the standard 50mm lens, an integrated lightmeter, and film advance by a lever. This effort to modernize the line failed, and these cameras are veryrare today.
