Most zooms do have linear distortion, though many have
one point in the zoom range where distortion is minimal.
Most Nikkors have moderate distortion, and a few have
almost none (28-105mm f3.5-4.5, 100-300mm f5.6, and
35-70mm f3.5, later version). Most WA and "normal"
non-zooms, and a very few teles, also have noticeable
linear distortion (exceptions: Nikkor 15mm f5.6, 21mm
f4, and late 50mm f1.8). BTW, most viewfinders have
linear distortion of the "pincushion" type (the others
are "barrel" and "wavy-line/moustache"), so it is
hard to use the camera's viewfinder for judging lens
distortion...
