Thanks for the affirmation Klaus. If I find it difficult to detect obvious de-centering at f/5.6 for the wide-end and f/8.0 from mid-range on then I'm buying this lens (assuming it's fine in other regards, such as AF functionality, external condition etc).

Well, depends. All it takes is flat scene at a longer distance. That's not exactly a shop scenario though.
I will try a little centering experiment this evening with you folks which includes a very basic test. That'll be interesting.
