Jupiter-8 50mm f/2 (Serial: 017179) – Standard Rangefinder Lens (Contax/Kiev or L39 Mount)
The Jupiter-8 50mm f/2 is a classic Soviet-era lens produced by KMZ and later by other factories in the USSR, based on the renowned Zeiss Sonnar 50mm f/2 optical design. It delivers beautiful, characterful images with smooth bokeh and a slightly soft rendering at wide apertures, making it a favorite among vintage lens enthusiasts. Compact, all-metal, and built to last, the Jupiter-8 pairs perfectly with many rangefinder cameras and can also be adapted to modern digital systems.
