They are all first-rate lenses over most of their focus ranges, with
declining image quality at wide apertures as minimum focus-distance
is approached. At medium to long focus distances, they are fine
to the corners even wide-open. BTW, their optical designs are basically
the same (so the similarity in performance is not surprising).
