I have Konica Hexanon 50mm f/1.4 for sale. This lens is quickly becoming extinct and will definately increase in value if you hold on to it. I am trying to raise some cash for Panasonic wide angle and therefore, unfortunately, selling this gem. Look at my ebay listing: Konica Hexanon 50mm f1.4 lens great condition! - eBay (item 190511753323 end time Mar-20-11 00:17:49 PDT) Will sell off ebay for $95 shipped (incl. paypal fees).
