Lens decentering generally is much more obviosu at close ranges than at long ones.[/quote]



I assume that shooting at long distance is used to test the tilting problem of a lens. If a lens is perfectly aligned itself but the optical axis is not perpendicular to the sensor plane (I don't know what is the factory tolerance for this) then a tilting effect will be easily seen at long distance.
