Why not skip the zoom, and go for the highest optical quality?
The 20mm f2.8 Nikkor is first-class, and you already have the 35-70.
I find that super-wide zooms are disappointing for mid/close work,
since it is easier/faster to just move yourself ("foot-zooming")
for framing under those conditions. For infinity subjects, or in
situations where your mobility is limited, the zoom may be useful,
but if you are critical of image quality, the super-wide zooms
(at least the, uh, "cheap" ones...;-) may not serve for landscapes
as well as a fine prime.
Hope This Helps
