I just answered this post...:

If you mean at any aperture the zoom and prime have in common, the
answer is no (though the 75-150 E and 80-200 f2.8 are close). If you
mean in the range of f5.6 and smaller apertures, the 35-70 f2.8, some
samples of the 35-105's, the 50-135, probably the 50-300 ED, and most
of the 70/80-200/210's come close, among others. If you mean at optimum
apertures, then many more can be added to the list...

To this I will add that a few low-end lesser-capability zooms seem to
have been added to the AF line...
