Leitz Elmar 5cm f3.5 lenses were the standard lens for countless Leica thread mount cameras. They're small and light, and collapse down to almost the size of a body cap when not in use. There's a reason they were so popular! Very minor cleaning marks and light coating etching on the front element of this one, like nearly every Elmar, but nothing that would cause any imaging issues. Cosmetic condition is very good, with light barrel wear. SMooth focusing, good diaphragm. Includes front cap.
