That's one potential effect - one or more elements are more or less centered (the center is where it should be) but tilted.
The other one is a more a global loss of contrast caused by an off-center (shifted) element and that's harder to check in shops.

Thanks Klaus
With your rating of Tokina and caution re Ulra Wide Angle lenses in mind, (how) would you consider buying the 11-16mm..? PZ gave it a very good review, but this has me wondering. Has Quality Control dropped badly since that review - seems that way, maybe? With Nikon at the other end of your QC scale, maybe the 12-24 looks an (expensive) better bet?
