For sale is a Leica 40mm summicron. Some dust specks in there and there is a spot of pin head size at rear element that I'm not sure is dust or mark. No haze. Very clean glass consider its age. Body has some paint lost but nothing serious.
It's modified to bring up the 35mm frame line on your M cameras.
I'm selling the lens alone for $3800.
If interested, please drop me a PM for further details.
