Not really a question, and I don't know if this has been mentioned before (it didn't show up in a site search), but a nice picture of not one, but two, lost forever rarest of the rare FD lenses. As I understand it there were a few, less than 20, 1200 f5.6 FDn lenses made, they were not sold but went out to the professional networks for various countries to lend at special occasions. They first appeared at the 1984 LA Olympics and that is where this image is from. Of course the EOS system came out just two years later, at this point all the FD 1200mm f5.6 L lenses went back to Japan and the glass was re-bodied into the first of the EF 1200mm f5.6L EOS lenses, they were available for special order and several pro divisions still actually have theirs. That is a 400 f2.8 L next to it and a 600 f4.5 just below that. Link.
