This lens is out of my personal collection.
The 5cm F2.0 collapsible Summicron Screw lens from 1952 is one of the RARE THORIUM lenses. It is beautiful. Focus is smooth, Aperture click stops are positive. Cosmetically excellent. Glass has the brown tinge & beautifully clear (shine a very bright light through it & it will show slight dust marks consistent with age). Overall a beautiful lens. It is being supplied with Leica plastic keeper & IROOA hood & cap in original box
