Overview

The Isco Gottingen Isconar 100mm f/4.5 is a simple, slow triplet lens with a classic rendering that appeals to users who enjoy older optical looks (MFlenses). Its build is described as beautiful but with potential handling issues: one user reported a heavy focus and a loose focusing ring that required jamming to engage, solved by mounting on a helicoid adapter (MFlenses). Optically, it delivers pleasing results, especially stopped down to f/5.6 or f/8, and is considered a good value (MFlenses). It suits photographers who appreciate vintage triplet character and don't mind manual handling quirks.
