Strange to come across this post, as I was the winning bidder, I actually bid because it had a mark on the coating a I know it little effect on the IQ, well not detectable to my eyes anyway, but it does put people off on ebay, so I thought it might go for a good price. Should arrive tomorrow so i'll run a film through at the weekend. I have to say I've had a great experience with the 25/2.8, hopefully this will have similar qualities......Robert.
