Return of the Lense.
After it has been readjusted, it has become very sharp. Very good at F/2.8, and razor-sharp from F/5.6 and up - only below my girlfriends 100mm macro.
As a rare exception, I'd like to mention Japan Photo in Aalborg C for their exceptional customer care. It's a great thing to know you can trust the people you buy your gear from.
