Do I qualify?
You're off to a slow start. I have 50 Fifties. One member here had (until recently) more Fifties than I have total lenses, well over 200. Of mine, 5 are duplicates and will go the the selling block when they're worth selling (M50/2s and Cintar 50/3.5s are about worthless now) but the other 45 all have their uses.
Some seeming-duplicates are actually different enough to keep: My Meyer Oreston 50/1.8 has its aperture pin glued down for use on my K20D, while its twin Pentacon Electric 50/1.8 has the pin free for use on M42 cameras; and the big black M42 CZJ Tessar 50/2.8 (5 iris blades) is quite unlike the little alum Exakta-mount version (12 blades).
