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 Z-500 This lists the specs of the lens. Or will sell for 200 cdn. Canon AV-1, very good condition, 20 cdn. Canon AE-1, no battery door cover, useable conditon, 10 cdn. Canon power winder A and case, there is a small superficial crack, and one spring in the battery pack missing, does not affect use, 10 cdn. Canon FD mount 50mm f1.8, no scratches, haze or fungus, barrell shows signs of use, 10 cdn. Pm, or email email@example.com for photos etc.
