Soviet 135mm f/3.5 telephoto lens by LZOS/Arsenal, based on Zeiss Sonnar design with lanthanum glass for warm color rendering and creamy bokeh.
Technical Details
The Jupiter-37A features an aperture range from f/3.5 to f/22 with 8 aperture blades and a minimum focusing distance of 1.5 meters. The filter thread is 49mm, the lens weighs 430 grams with a length of 95mm. It was primarily manufactured in the LZOS (Lytkarino) and Arsenal (Kyiv) plants for M42 screw mounts and later also for Pentax K-mount. The construction uses lanthanum glass for improved optical properties, resulting in a characteristic color rendition with warm mid-tones and smooth transitions.
History & Development
Development began in 1958 based on the Zeiss Sonnar 135mm f/4 from the 1930s, whose patents became available after World War II. In 1960, series production started with the first version, Jupiter-37A 135mm f/3.5. In 1975, a revised version with improved coating followed, recognizable by its greenish-violet reflection. The last production series from 1985-1992 received multi-layer coating and optimized mechanical components.
Practical Use in Film
Eastern European film productions from the 1960s to the 1980s regularly used the Jupiter-37A for portraits and medium shot sizes. Its characteristic bokeh quality with creamy out-of-focus areas made it particularly popular with Soviet cinematographers. The lens exhibits slight vignetting and soft contrast at wide apertures, which become significantly sharper from f/5.6. Modern filmmakers appreciate it for its vintage look with warm color rendition and the characteristic "swirly bokeh" in certain subject situations.
Comparison & Alternatives
Unlike the sharper but more expensive Zeiss original, the Jupiter-37A offers a softer, more organic look. The Helios-40-2 85mm f/1.5 from the same era is faster but less versatile. Modern alternatives like the Canon 135mm f/2 or Sony 135mm f/1.8 GM are technically superior but do not achieve the specific vintage characteristic. The Jupiter-37A is primarily used today for creative projects where its distinctive look is desired.
