Perception....
While true, it does not change the optical performance (characteristics) of the lens itself,
the area the sensor sees is smaller, so if one prints a 4x6 from each camera with the same lens (at the same setting if a zoom), the one from the crop sensor camera will appear to be a "magnified" or "telephoto" version.
Semantics.
If it actually increased sharpness, I would agree. In any case, it is the photographic equivilant of "Fools Gold".
You are just blowing up the smaller DX frame to match the already 4x6 FX frame.
