Depth of field is sort of hard to accomplish with wide angles, as you are traditionally capturing many subjects within a scene, and having them all in focus is traditionally desirable.
i'm a low light nut, as I don't have an external flash, and prefer the look of natural lighting. I was pretty hesitant buying a slow lens, but remember, exposure is a blend of ISO, Aperture, and shutter speed.
being a lens, we can get rid of ISO as a part of the equation. the lens has nothing to do with ISO. so, the elements of exposure that still apply are aperture and shutter speed.
traditionally, with mid-range zooms and such, the only way for a lens to be a low light performer (without optical stabilization of some sort) is to have a fast aperture (f/2.8 or better, for example).
applying the rule of 1/focal length for a minimum shutter speed to minimize camera shake, wide angles shine. at 10mm (with the 1.5x crop factor, 15mm on a DX body), shutter speeds of 1/15 sec are enough to eliminate most camera shake. this rule really makes sense when you're at 300mm, trying to keep the image stable. longer focal lengths require shorter shutter speeds.
so, therefore, the slower aperture (f/4-5.6) is negated by the focal length, allowing for slower shutter speeds.
that's originally what I was planning on. however, i realized that I don't really need 2.8 for a wide angle lens, and that's a pretty limited range.
the 11-16 is ~$569, and I just checked today, and the 10-20 is $421 @ amazon.
I'm convinced I have an updated version... doesn't look like any of the other 10-20's i've seen. performance seems to be enhanced as well.

Great shots!!!! 
I shot table shots at events with a wide angle. 17mm. I have 6 of the 12 people at the table get up and stand behind the others. The edges get a little distorted, but it sure helps due to not having enough room to step back due to being in a packed ballroom turned dining room.

not really.

WOAH...
Those pictures just unearthed a memory from the depths... I went to that greenhouse/botanical gardens/whatever-the-hell-you-call it when I was like 3 or 4. I had totally forgotten about that :loco:
