What are good wide angle lense for Canon Rebel T3i?

He was born with no arms and legs. Now, don't you feel bad?

lol, just kidding. He was standing behind the wall the others are sitting on. : P Hey, give me a break. This was a quick, down and dirty freebie. It does however, demonstrate the capabilities and distortion of the 10-22.

Try the Sigma 10-20

This. Sold mine recently, but only because I upgraded to full frame (it does still work on full frame, mind you, but just has a ton of vignetting. Physically attaches though). While I had it, though, this was a really sharp, affordable, massively wide angle lens, with great build quality, a focus distance meter, and all sorts of fanciness.
