Facebook is demanding that I give them my Cell Phone Number. That ended my Facebook account.
I picked up a Canon 5cm f2 Serenar in Leica mount last week at a Photorama show for $50. Needed a little work- much better performer than I expected. Learned a lot about it from Peter K's site from the Wayback machine, more than anywhere else. Also picked up a late 50/1.9 Serenar- it was hazed over, and had lots of paint shards floating around- thought they were the blades. Also cleaned up nicely. I took the Canon 5cm f2 and a fairly early Nikkor 5cm f2 out this past weekend-

I also have the Nikkor 5cm f2 in collapsible mount, made within months of the Canon. The Canon III that I bought had a 1949 Nikkor 5cm F1.5 on it. My Canon 5cm F2 is from 1949, as is my early Canon 50/1.9. I picked up an early Leotax D-IV with the Simlar 5cm F1.5 on it, also occupied Japan. Tracking down real information on these early lenses is not easy, being able to inspect and use them -and take them apart- helps understand them.
