I actually wrote a blog about shoosing the right lens about 2 weeks ago.  In it, there's an image that I shot with the Canon 16-35mm L IS.

You can see it here... <photo link>

Even though it was shot on the 5D MkII and was at 16mm focal length, it didn't seem to show the vignetting that it does at full aperture - this image was shot af f22.

I'm sure there's some complicated optical explanation for that, but I just try to avoid shooting at full aperture - unless I want to vignette.

Good point Charlie.

Vignetting along the corners of images captured with ultra-wide angle optics can often be greatly reduced by stopping the lens down 2-3 stops, which also improves the overall sharpness of the image.
