I looked at the 50mm 1.4, as well, but - as I said - 50mm really isn't wide enough for indoor photography. The 17-55 f/2.8 may work, but I was really looking for something even faster than that. I don't know, I want a fast lens to take good photos (hopefully 1/25 and faster) in low light with as low of an ISO speed as possible (100-200), but I suppose with the camera's high-ISO noise-reduction, an ISO of 400-800 wouldn't be the end of the world. What's f/2.8, anyway - 2 full-stops down from f/1.4? That's a quarter of the amount of light being let in, so I'd have to compensate by quadrupling the ISO or shutter speed or doubling the ISO and halving the shutter speed. Grr... probably putting too much thought into this.
Though a zoom lens would also be a definite plus, and the f/2.8 is wider...
Edit:
Ooh, fixed aperture throughout the focal length, very nice. Though I suppose that should have been a give, seeing as it's a 17-55mm
f/2.8 (and not f/2.8-whatever).
Edit:
Hm. Didn't realise it, before, but the 17-55mm f/2.8 would pretty much replace my current 18-55mm f/3.5-5.6. This is looking more and more promising.

All for a considerably smaller price-tag (especially considering it's currently got an instant rebate in the US!). This just might be my next lens.
