Overview

The Schneider-Kreuznach Retina-Curtagon 35mm f/2.8 is a compact, all-metal German lens with smooth focusing and organic rendering. Its shift variant offers a unique but fragile shift ring that can be accidentally activated. Optically, it shows visible barrel distortion, worsening with shift, and requires stopping down to f/11 for best results. It suits street, travel, and characterful photography, especially on mirrorless via adapter, but buyers should check optics and infinity focus.
