when to return a lens for new copy?
Thanks for the link. Can you say more about why you sent the first two back? Just didn't seem sharp enough to you? Mine doesn't look as sharp as I think it should but are there tests I can do to know for sure? I don't want to send it back if this is as good as it gets.
