How about a 20mm f2.8 Nikkor and a 35mm f2 Nikkor instead? If you
stick with used lenses, the total price may not be too bad, and the quality should be higher than even the Nikkor 20-35mm zoom. Also,
it may be worth borrowing a similar focal-length range zoom to play
with before purchase to see if you come to the same conclusion I did:
tele zooms are very useful; mid-range zooms are moderately useful;
wide zooms are close to useless, since it is often faster and easier
to move instead of adding the zooming step when shooting at close
and medium distances. (And for reasons I have not yet figured out,
wide-angle zooms are decidedly unimpressive in their apparent zoom
effect when zoomed through their range - this conclusion from a
wide-angle nut who believed in the distinct "personality" of each
and every fixed wide-angle focal-length, and who owned all of them!)
BTW, I tried a Sigma 21-35mm and a Vivitar 17-28mm, and the term
"pop bottle bottom" was not far from mind while checking them out -
good single focal-length wide-angles are hard enough to build,
let alone good wide-angle zooms, let alone good cheap wide-angle
zooms.... Why trade high optical quality for the minimal advantages
of a zoom?
Hope this helps.
