I'm asking this because Ken Rockwell states that FF can a make a crappy lens to be in a level equal or above a relatively good crop lens (at least, this is what I understood from one of his articles).
A cropped lens of a full frame body may not work too well since the image circle may not be large enough to cover the FF sensor size.
On the other hand taking a Full Frame lens that may be less than stellar, may be a wonderful performer on a cropped body, since the smaller sensor will only be using/seeing the center part of the lens, which is usually much sharper than the boarders and corners.
