Seems like there is no love for the 17-35 f2.8.....never got to try that, but reviews have been mixed on this lens. Any actual user comment? :think:
As Blur Shadow mentioned, it's sharp in the center with weak corners. Still pretty good though. Resized:

Center is pretty sharp at 100%.

Corners are not so good though at 100%. But edges are fine.

One thing to note is that colours are somewhat muted and neutral, lacking some of the pop and micro-contrast of the newer lenses. But hey, this lens design is 13 years old and is still ok on the D800.
