    Overview

    The Jupiter-9 85mm f/2 is a Soviet-era copy of the Zeiss Sonnar, known for its low weight and aluminum build, though sample variation can cause stiff focus rings. Optically, it is soft and low-contrast wide open, improving by f/2.8 in the center and f/5.6 at midframe, with corners sharp at f/11. Vignetting is low at 1.6 EV wide open, but flare resistance is poor. It suits portrait photographers seeking a vintage look, but not for landscape or architecture.
