If the above lenses were OK for your purposes, you will love the 24-120.
At f8-16 it is a really first-class lens (easily beating the above in
sharpness), and the distortion level is moderate throughout, though
never "0", and often compound-curve... BTW, all Nikkor primes 60mm and
above have no linear distortion (true also of the 15mm f5.6, 21mm f4,
50mm E/AF/compact-AIS, and 55mm macro).
