GOI Zenit M39 Jupiter-30 2/85mm (OB-322) prototype

At the same time that Asahi Pentax introduced the first “SMC” (Super-Multi-Coated) lenses and Carl Zeiss Jena had already begun producing multi-coated (MC) optics, the State Optical Institute (GOI) in Leningrad also embarked, around 1971, on the transition from single coating to multi-coating technology.

The Jupiter-30 was conceived as the successor to the well-known Jupiter-9 2/85mm, designed for M39 FED/Zorki rangefinder cameras as well as for early Zenit SLRs. However, as we know today, the Jupiter-30 was never released under this designation as a production lens – only many years later did another, unrelated lens appear under the same name.

The example offered here is an original prototype, in very good, fully original condition, with perfectly clean optics. Although it carries no MC marking, it shows a distinctly different and remarkably refined coating compared to the Jupiter-9, making it a truly unique collector’s piece. It is offered together with a Zenit-C camera no. 58158298.
