It depends on your photography: UW photography is difficult since `there is always stuff' in your images you don't want to have and the effect gets old really fast. I'd probably get a portrait lens.
I think you could pick up a 17-35 mint for $300-400 less than the 14-24, but that's only if money is a factor. One thing I do like about the 17-35 is it's non-G. I like the aperture ring, and ability to go back and use film bodies, and no built-in AF motor to break (and I've had two lenses that had AF motor failures (one a Canon, one Nikon.)
re. the 200mm etc suggestion: it was a joke. He seems out to spend £$ rather than meet a specific photography need.
No, I'm out to meet a niche photography need, I have funds coming in (profits from photography sales) and I'm grappling with which niche I should address first. Thanks for the nice words though

You really haven't specified what is most important to you other than filling some niche areas. That above all else should be factoring into anyone's decision above focal length overlaps, etc, etc.
Personally, although the 14-24 has an excellent reputation, I would want it for landscapes. And for landscapes, I consider the ability to use a polarizer essential because it is one filter you cannot duplicate the effects in post. So that makes it a deal killer for me. I already own the 17-35 anyway.
I stand corrected. Nevermind.The 17-35 does have a built-in motor, as despite being a non-G lens, it is still an AF-S lens. Moreover, it is known to develop a squeaking noise that may/may not go away and may contribute to AF motor failure.
Really, there have been more than a few shots lately that I have taken for a project I'm working on that could have benefitted from a wider lens, that project will run through the end of the year. The portrait lens would just provide a nice specialty lens for some other work my wife and I do. I think that I could get some good use (maybe not a ton of use, but good use) out of either lens. It's merely a matter of priority at this point.
It's such an odd question, since only you can answer it. How should we know what your priorities are?
