Overview

The Isco-Göttingen Isconar 135mm f/4 is an older lens that requires little post-processing, according to Attila, but is not top-level. It has a distinctive look that attracted attention in Jerusalem, as noted by inombrable. Sharpness is decent at f/5.6, while wide-open portraits show softer rendering. Build quality is solid, with a classic design. This lens suits photographers seeking a vintage character for casual or street photography, but may not satisfy those demanding modern optical perfection.
