No,that was 10 years ago but again, Icalled them up first. I had bought a barain f/5.6 250mm lens on ebay and when it arrived it had a clear rattle sound inside as if sll the glass elements where lose. They fixed all of that, adjusted it on their optical bench and sent it back with a repair eort, all for $50; amazing customer service!. I did lived in Germany at the time.
Call them up first. If you have a German-speaking friend, have him or her do it! You cannot count on getting in touch with an English speaker. I spoke to an elderly very-friendly gentleman.
