At 16mm it really is much wider than the Canon 17-40mm f/4 L or any other top-brand zoom. On the full-frame cameras for which it's designed the 16mm is worlds wider than my Nikon 12-24mm is on the 1.5x sensor cameras on which the Nikon works.

If you shoot film, or there's a full-frame digital body in your future, then I can recommend the new Canon wide zoom to you without reservation.

The EF 17-40 generally gives slightly sharper edge performance with less chromatic aberration than the EF 16-35. However, differences are small.

My recommendation is that if you already own the 16-35mm f/2.8L there's no need to change. It's "six of one half dozen of the other" when comparing the two in terms of overall image quality, and the extra stop in speed may well be important to you.

I personally regard the Canon EF 16-35mm f/2.8 L USM Lens as the best full-frame Canon ultra wide angle lens available.
