    35mm · f/2.8

    Overview

    The Jupiter-12 35mm f/2.8 is a Soviet copy of the Zeiss Biogon, offering a unique character at low cost. Optically, it provides decent center sharpness from f/2.8 but suffers from significant field curvature, requiring f/8 for decent midframe and f/16 for corners. Vignetting is low, but color cast is a notable issue. Build quality is inconsistent due to wide manufacturing tolerances; the aperture ring is inside the front barrel and doubles as a filter ring, which can be awkward. It suits film shooters seeking a vintage look on a budget, but digital users may find corner issues problematic.
