For sale is my Leica 90mm f/4. The lens barrel is in good condition, except for some chipping of the vulcanite (see picture). There are some imperfections in the finish (see flashlight test in flickr), but you have to look hard to see them. For its age the lens optics is in pretty amazing condition. This lens has a detachable head that can be used with the Viso system. May be usable as an enlarger lens too. Comes with a third-party front cap.
