Re: 16-35mm f/2.8L II possible lens blur problem

For some reason I can't get the posted images to enlarge so I can look at them closely, but this sounds like a classic case of a lens element knocked out of alignment. The 16-35 f/2.8 is already pretty soft at f/2.8 in the corners, so a misaligned element is disastrous. You can verify this problem with the newspaper on the wall test, but I'm pretty sure it needs fixing.

Good luck!
