When it comes to German post-war lenses there are so many varieties some of which are ultra rare and nobody cares for some reason. Rare mount varieties, newer revisions in low production numbers, identical lenses where one has more aperture blades and similar small changes. I guess lens collectors have to draw the line somewhere. I have a Schneider-Kreuznach Edixa-Xenon 50mm f/1.9 m42 late version which seems to be quite hard to come by, but does anyone care? No. Could also be because it does not look cool.
