If you have a look at the sample image section most of the wide angle images show the field curvature issue.
Now if the lens does not perform in field conditions (unless you stop down to f/13) I don't really see how I can give it a good rating here.
The Nikkor isn't stellar in all aspects either but it doesn't seem to behave in such an extreme manner on the D3x.

Hi Klaus,
Let me start off by saying I'm not a zoom person at all. Not even Nikon's 14-24 or Canon's 70-200 2.8 IS II impress me. So it goes without saying that I have very little regard for the 24-70L.
However, the thing I want to understand better in your review is what should really be blamed for the behaviours that you observed. I understand how you discovered a difference in the field when you focused to infinity... but when considering all things practical, even f/11 at 24mm is enough on a 5D2 to get everything from 2m to infinity in complete focus at 100% view (from my experience). A part of the DOF function, as you know, is the viewing magnification and a 100% view of a 21MP image reduces DOF greatly.
Again, I'm not disputing what you've found here. What would be ideal here is you choosing the perfect/your favourite lens for this focal length (~24mm) and giving us a side-by-side comparison. This way we can see how much blame should go for the lens and how much should go for the DOF.
Also, in all fairness, I think the 24-70L is not that bad, for the zoom it is. If I wanted the best quality for any photographic application, I can't think of any zoom that I might choose over a prime. IQ-purists/aperture-junkies like me aside, anyone who's serious about landscapes wouldn't use this lens either. With the 24-105L IS around, the 24-70L is not the best choice for holiday/"everyday"-shooting either. These points have been established a long time ago and also by your review. So that leaves us with the question: How will this lens perform for the people who want to shoot at f/2.8 in the 24-70 range, against comparable lenses?
Thanks again for the reviews...
