Yesterday I picked up a rather hard to find Canon 7Sz. While congratulating myself on my luck, I saw an interesting lens on a shop shelf, it turned out to be a Nikkor O 2.1cm f/4 lens for the Nikon rangefinder cameras. It had the original finder and case, but was missing the rear cap. I parted with the rest of the cash I was carrying in my wallet, and walked out with the lens. I am now shooting with it on my SP,
