Conclusion: I bought some days before the 16-35L II USM and im very unlucky with it. This Lens is less sharp than the 17-40 4.0L. See the Link to the picture. Did someone made the same experience ? What do you think about this compare ? Both images made at f4.0 ISO100 16mm/17mm EOS40d. I olmost send it to the Canon service, bud it came same bad back!! I think I go buy the 17-40 4.0L wich I olmost resaled.
Cons: sharpness in the corners !!!!; price; focus ring bad accesable.
Conclusion: I have now tried 3 different copies of this lens, and i have returned all 3 of them. The images are so soft, that they are not usable for my purposes. I have done the testing with a D60 and a 10D. I suspect that the results in the corners will be even worse on a fullframe-camera.
