For about $750 you can get a brand new Tokina 16-28mm f/2.8 Pro FX Lens for full-frame Canon. Great third party alternative for a much lower price. The only caveat is that you can't use filters with it and some say it is flare prone. I personally never tested it.
Just read a review claiming that it's the second sharpest UWA zoom after Nikon's 14-24; but that review also cited it's issues; it's heavy, it doesn't take filters as Fred mentions above, but also that it has a very short (<2x) zoom range, with a slower autofocus than Canon's.
If you need UWA sharpness and can live without conventional filters or intend to use unconventional filters like a Big Stopper, then it's likely the lens to get for the price.
For me, though, I'd rather have the 17-40L. Light, small, takes filters, wide zoom range, inexpensive, and sharp enough for my purposes, such as wide-open indoors and stopped down outside, with Canon's AF; I'd be using it on a 6D, so the loss of a stop doesn't bother me too much, especially considering the primes I have in that range (24/2.8 IS and 40/STM), along with the coverage of the 24-105L.
If the Tokina took conventional filters, it'd be a total win; but without that feature, along with the risks it entails, I'd rather have the slower Canon. Weight and size don't bother me as much (yet).
