    Overview

    The Jupiter-3 50mm f/1.5 is a Soviet copy of the Zeiss Sonnar, offering a fast aperture at low cost. Optically, it has average sharpness wide open and low contrast, with noticeable softness and a greenish color cast on some copies. Bokeh is unremarkable. Build quality varies; early versions may have stiff focus, but a CLA improves handling. It suits budget-conscious rangefinder users who value speed over clinical performance, but calibration issues make it hit-or-miss.
