A lot of people go for the 17-40 F4 L or those willing to spend a lot more for faster glass buy the 16-35 f2.8 L version 2. One other choice I like is the Sigma 12-24 but that's really wide on a full frame. With that said I've never felt the 17-40 L deserved / lived up to it's price (and yes I have one plus the Sigma)
It really depends on your budget and what purpose.
If you like to take landscape photographs and have all in the time in the world, I would choose prime lenses
If you like to versatality and just mainly focus on AF then I would choose zoom lenses.
(remember primes have superior quality to zooms, but zooms got the versatality, therefore you have to sacrifice either one)
Personally I would push for the 16-35 or the 35 1.4
Hope this helps

Most of photography is use orientated. I f you have good equipment. The rest is up to you.
I recommend the 17-40mm f4 L. Yes, on a focus target, the 16-35mm f2.8 L is probably better. In the real world of photography, I doubt anybody can tell the difference. Plus the f4 to f2.8 L is only one stop. One stop is not a deal breaker or maker, most of the time.
The 8-15mm f4 L is by far the most fun lens to have. And like I said it ia all bout how the photographer, you, uses it.
This lens may not be the most practibile but it is a ball to play around with. Get the 17-40mm f4 L and you won't go wrong.
