Thanks, hmm, I'm surprised you aren't happy with the sharpness wide open
and surprised it got damaged as it's supposed to built like a tank. I
found another review actually of the 17-35:
http://www0.epinions.com/content_86995668612
which explains the differences are mainly the extra 3mm obviously and
closer focusing on the 17-35 and better control of flare and ghosting,
which is pretty important actually. Big price difference though. I don't
see the need for AF-S for a wide lens.

This one rates the flare control as great, but corner softness wide
open. Hmmm

Paul,
On the positive side, the 20-35mm f/2.8 AF Nikkor was probably my
favourite Nikkor. At every focal length except 28mm, it performed
better optically than the comparable fixed focal length Nikkor. Only
the 28mm f/2.8 AF-D Nikkor would beat it. The 24mm f/2.8 AF-D Nikkor
merely equalled it. The 20mm f/2.8 and 35mm f/2 AF-D Nikkors did not
come close, except the 35mm gave an extra stop compared to the zoom.
On the negative side, there is considerable sample variation. The
glass aspheric element was hand ground. Poor samples exhibit
noticeable colour fringing, and that's on film. On digital, this
would presumably be even worse, although I only ever got to try the
lens on film. My samples (I had two at various times) did not suffer
from this, however.
I'm not sure that a 20-35mm focal length range on an APS-C sensor is
going to be much use, giving an equivalent 30-48mm.
If you want to buy one, you should either try before you buy, to test
for colour fringing, or buy from a seller with a good returns policy.

Well, I never got a kit lens and I do have a 12-24 & 70-200 so it would
fill a gap for me. Not sure I want a big beast for walk-around use though.

Yeah that would be possible with the $750 one. Sounds like a certain
amount of CA is unavoidable though.

Don't be such a pessimist!
Both my samples were free of any sign of CA. As often seems to happen
with pro grade Nikkors**, the later production was better. So avoid
the pre-D versions and go for the one with "AF Nikkor 20-35mm f/2.8D"
on it, and you are much more likely to get a good one.
[**Early examples of the 17-35mm f/2.8 AF-S lenses were atrocious.
Nikon improved the quality of manufacture. A few months later, the
lenses were consistently excellent.]

It's the color fringing which doesn't help.

Oops. You're right. I got the focussing problem confused with my
plasticky 20mmf2.8. :((
No problem with focussing on the 20-35...it is built like a tank. At
the moment, I just can't justify buying the 17-35 when I can get away
with stopping down to f4.8 for most of the photography I do.
