The 16-35 L is about as good as it gets for a wide Canon zoom. I
normally stop it down 3 stops or more on the 5D. Many times the
24-70 L is as wide as I need and a more versatile zoom. Some say
the 16-35 is over priced, but I would buy it again, rather than the
17-40. I like it when I need it.

But since you normally stop it down, is there any advantage over
the 17-40?

Even when stopped down, AF uses a f/2.8 aparatur to obtain lock up. Lens above f/2.8 can't take full advantage of the AF system. Low light lock up is noticeable faster and more possble.

It's wider too, that silly 1 mm longer.

Everyone I know that has one, likes it. I see no sense in putting slow lens on EOS cameras, they'll shoot ok in brigt sunlight, but a quick AF lock means less lost shots.
