How rare are modern silver M wide angle lenses below 35mm? Specifically the Elmarit 21mm f/2.8 ASPH and Elmarit 24mm f/2.8 ASPH? What is the total count of the two? How about Summicron 28 ASPH? The latter is apparently not brass...? How many silver chrome Summilux 28's were made before they were discontinued? Any silver Summilux 24's? Was there ever the SEM 21mm Super-Elmar ASPH f/3.4 in silver? What about Elmar 24 f/3.8 ASPH? I have also seen a silver MATE but no WATE? And the silver Elmarit 28mm f/2.8 ASPH was finished in 775 pieces only?
