Hmmm, the AF-D 35-105 Nikkor is not the same optical design as the
35-105mm AIS and non-D AF, and is supposed to be quite good. BTW, good
samples of the earlier 35-105mm are excellent, but sample quality
with that lens is quite variable. The 35-70mm f2.8 is good (not as
good as its reputation, I think...), but the zoom range is uselessly
moderate. I found the 28-70 OK, and nicely consistent across the frame,
but not ultra crisp. The 28-85 is good. You might want to consider the
24-120mm f3.5-5.6 AF-D (under $600 in the US, discount price) - the
one sample I tried was surprisingly crisp (and similar in speed to most
of the other lenses mentioned if you stay shorter than about 85mm...).
BTW, virtually all zooms show some linear distortion throughout most
of their ranges, but Nikkor zoom distortion is moderate (and similar
in amount in virtually all Nikkor zooms).
Hope This Helps
