14-24 f/4 makes no sense whatsoever. 17-40 is perfectly fine for all intents and purposes.
All your intents and purposes, perhaps.
UWA's distort people waaay too much for my taste, and in such an unflattering way. I'm seriously contemplating picking up an 8-15 fishy for UWA purposes instead of a 17-40 or 16-35.
I'm struggling to reconcile those two sentences!
