Taking this a little further Mark, Does this infer that any lens , known 
to have poorer resolution towards
the edges when used for 35mm, could in fact be a "good lens" when 
attached to a DSLR, as only a part of the image circle is actually used?
I've often heard that people use adapters to attach MF lenses to 35mil 
cameras for just this reason.
