Canon 11-24mm f/4L USM Hands-on Review by DigitalRev

There are ultra-wides and then there's this - the Canon 11-24mm f/4L USM (http://bit.ly/Canon11-24mm) . At its widest of 11mm, and a completely rectilinear wide-angle too, this is wider than a lot of lenses out there.

But is this is monster ultra-wide zoom as good as it sounds?
