Zeiss's manual-focus Biogon 35mm f/2 for Sony FE — wide-angle Loxia with classic Zeiss rendering.
The ZEISS Loxia 35mm f/2 Biogon T* launched in 2014 alongside the 50mm f/2 as the wide-angle option in the Loxia manual-focus range for Sony FE mount. It uses the Biogon optical formula known for minimal distortion and even illumination across the frame.
Optically very good — the Biogon design delivers low distortion unusual for a 35mm lens. Sharp from f/2.8 with pleasant wide-open character. T* coating provides excellent flare resistance. Focus transition is smooth and gradual — a hallmark of quality manual-focus lenses.
Sony FE mount with 52mm filter thread. Weighs 340g. Weather-sealed construction. De-clickable aperture ring for video. Manual focus only with electronic EXIF communication. Minimum focus distance 30cm. Metal construction throughout — premium feel.
Available used at mid-range prices. The Biogon formula is traditionally a rangefinder design adapted for mirrorless — purists appreciate the optical heritage. The Zeiss Batis 25mm f/2 is wider with AF. For photographers who value the manual focus experience and Zeiss rendering.
