I'm looking to trade my Tamron adaptall-2 200-500 6.9 for a Canon FD mount fisheye, preferably a full frame, not circular. The 200-500 is in mint condition, has both original caps and case. Zero fungus, haze, scratches and aperature works perfectly. Case is worn, but works well. Lens also has 82mm uv attached. Translated version of http://www.tamron.co.jp/data/old-lens/z500.htm This lists the specs of the lens. Or will sell for 350 cdn. Canon AV-1, very good condition, 30 cdn. Canon AE-1, no battery door cover, useable conditon, 30 cdn. Canon power winder A and case, there is a small superficial crack, does not affect use, 15 cdn. Canon FD mount 50mm f1.8, no scratches, haze or fungus, barrell shows signs of use, 10 cdn. Buyer(s) to pay shipping costs, prefer only North America Paypal is also preferred. I have 100% positive ebay feedback as well. Pm, or email email@example.com for photos etc.
