#1 Pentax SMC 55/1.8. Original K series.
I did an optical comparison with the more modern Pentax-F 50/1.7.
Comparison here: http://pdml.net/pipermail/pdml_pdml.net/2014-April/374955.html
Images here: Dead Link Removed
Some damage around the filter ring area but optically and mechanically perfect.
It's really a quite excellent lens.
$40 shipped.
#2 Rodenstock Rogonar-S 135/4.5 enlarging lens.
$50 shipped.
