Overview

The Jupiter-11A 135mm f/4 is a Soviet-era lens derived from the Zeiss Sonnar design, offering a gentle, film-like rendering with smooth bokeh and good center sharpness wide open. However, it suffers from significant veiling flare, even with a hood, and heavy corner darkening at wider apertures. Build is all-metal with a smooth focus throw but no aperture click stops, which can be accidentally moved. It suits photographers seeking a vintage character and willing to work around its optical flaws, especially for portrait or artistic work on mirrorless cameras.
