Portrait shooters who have used VERY wide angle for any reason to post a few sample pics? I'm building my gear, and currently have an EOS 40D, an old 28-80 f/2.8L that's still optically superb, and except for a battery and a 2gb flash card, that's it. I want to look into W/A for various creative reasons, but I just learned the wedding reception I am practicing for will be held in rather a smallish room (old stone-walled pub, pretty dark). My 28MM may not be able to catch group shots in this little space, and I'd like to see and hear how you pros have handled tight spaces with your lenses. I'm looking at the Canon 10-22 ($$$,) or the Sigma 10-20 ($), and fear they might be juuuust a little TOO wide. Of coure, lighting becomes an issue as well - I'm looking at grabbing the Canon kit that uses the ST-E2 remote and a pair of 580EX's, but lighting a scene that's ultra wide, even with a pair of lights...um, OK. I'm out of my depth already. Help me!
