I picked this lens up on ebay a little while ago. It was in very nice shape but stuck wide open. Not that uncommon for these lenses apparently. I was able to use it wide open, and get some very nice results, but I tried various ways to unstick aperture (short of opening lens up) and now I can not even attach the adapter to it. I would like to sell the lens + :43: adapter for $50 shipped. The adapter is $28 new, so if you are handy and can fix the lens it will be a helluva deal. You are taking the chance that it is not fixable. Given that, if my price seems off please let me know and make an offer. I am out of :43: for the time being, so I'd like to move these one way or the other.
