After the successful start of Kiev camera production in 1947, the GOI factory began developing interchangeable lenses for Kiev cameras. The focus was particularly on lenses that did not already exist in the Zeiss Jena Contax system, but instead offered different focal lengths and faster apertures. It was also important for the Soviet designers to demonstrate their ability to create their own advanced and competitive optical designs.
Around 1950, GOI developed its own fast portrait lens, the OB-57 Helios-40 (documented in the GOI Blue Book, p. 50.06). According to our research, only about ten fully completed prototype lenses were produced. However, this lens never entered serial production for Kiev cameras. Only about ten years later it went into large-scale production at KMZ for Zenit cameras, where it became one of the most iconic and highly appreciated vintage portrait lenses up to this day.
The offered lens is in fully working condition, with very clean optics and no issues. Included in the sale is a Kiev II camera (serial no.500051) of the same production period, also fully operational. It is quite possible that this camera was originally used at the GOI factory for testing this prototype lens.
