It cost a lot more than the original Kievs, and was sold in parallel. Which caused to have a comparatively short lifespan. The total production numbers are estimated between 8,000 and 50,000 units, making the camera quite rare. Lenses Some of those lenses are the same as Soviet m39 lenses for Zorki/FED rangefinders, but there are some exceptions. Orion-15 is a very rare lens in Contax/Kiev mount. Unlike the Leica screw mount version of the same lens, this one is not rangefinder coupled. There are multiple versions of Jupiter-8 lens available in Contax/Kiev mount. The -M version of the lens has click stops on aperture ring and the -NB version uses the external bayonet - it was introduced with Kiev 5, which doesn't have the internal one. The usual Jupiter-8 is the same lens than in m39. Helios-94 has the external bayonet and was available as a kit lens on Kiev 5. Not a lot of information can be found online about this lens, but it seems that it can't be mounted on older Kiev rangefinders - the focus scale of internal bayonet prevents that. There is some evidence online about people successfully modifying the original Contax/Kiev mount to accept this lens. Helios-103 is exclusively available in Contax/Kiev mount. It has the internal bayonet and was a kit lens on Kiev-4(A)M. The lens usually surpasses Jupiter-8 variants in reviews. It has greater resolution than Jupiter-8 lenses and it is also faster. Kiev 35mm SLRs Arsenal also made a range of 35 mm SLR cameras. They are not as well known as Zenit cameras, but they are still desirable for some of the innovative features they offer. Kiev Automat SLRs The unique Kiev Automat SLRs used their own unique lens mount; only a handful of lenses were available in that format. All these cameras use an unusual fan-shaped shutter. They are collector's items that were not exported. Kiev 10 Kiev 10 was one of the most innovative cameras produced in the Soviet Union. It was one of the first cameras that offered automatic exposure. It also featured its own lens mount, shared with its successors. The camera had a light meter, but it was a selenium one. Its accuracy declines with age. Kiev 11 A development of Kiev 10. Only small quantities of this camera were produced. The main difference was that the light meter was moved from the top to
