I have a Schneider digitar 90mm lens (copal shutter on a Linhof Techno board) which is noticably less sharp on the left side of the frame, shooting at f/11 with 33 megapixel back. I don't have problems with my other lenses so I think there may be some lens element alignment problem in the lens, or maybe some problem in the shutter thread.
I've heard that you can send the lens to Schneider and get it "recalibrated". I've searched the web a bit and found a service center, but they are of the not-responding-to-email kind, so I don't know if I found the right place.
Has someone got their lens recalibrated and can describe how it works, who to contact? And perhaps what it typically costs. The 90mm is a low cost lens so maybe it is cheaper to buy a new one than to get it recalibrated.
