Yes, at stops wider than around f8-11 (the zoom is
first-rate by f11, but the primes will give you better
performance at much wider stops). The 20mm f2.8 is a bit
better than the excellent 24mm f2.8, the 50mm f1.4 and f1.8
are equal-but-different-in-the-particulars wider than about
f4, and the 60 is none too good in the corners at
infinity-focus wider than about f8-11. More in my Nikkor
list - on my web page, under "I babble"...
