The Jupiter 9 85mm f/2 is the Soviet portrait lens that delivers Zeiss Sonnar quality at Eastern Bloc prices. Directly copied from the pre-war Carl Zeiss Sonnar design, the Jupiter 9 maintains that legendary rendering while being produced in quantities that kept prices low. It's the affordable path to classic portrait rendering, and many photographers prefer it to more expensive alternatives.
Verdict: The Sonnar for everyone. If you want classic Zeiss portrait rendering without Zeiss prices, the Jupiter 9 delivers. Quality varies, so buy smart, but a good copy rivals lenses costing 10x more.
Certainly one of the strong points of the lens.
Wide open the lens is somewhat soft and not really contrasty in general, but sharpness improves when stopped down.
The flare resistance is certainly nothing to write home about and the lens certainly shows its age here.
Moderate, not very high in general.
Surprisingly low at only 1.6 EV wide open and rarely noticeable further stopped down.
