Overview

The Jupiter-11 135mm f/4 is a Soviet-era lens derived from the Zeiss Sonnar design, known for its affordable price (often under $45) and all-metal build. Optically, it offers good center sharpness wide open but suffers from significant veiling flare, even on overcast days, which a hood only partially mitigates. It has smooth bokeh and a film-like character, but low contrast and corner shading at wider apertures. The aperture ring lacks click stops, and sample variation is common. It suits photographers seeking a vintage look and willing to work around its flaws.
