Well after about a month of frustrating over an ultra wide, I just bought the Canon 10-22. This was the most frustrating purchase I have made in years. I really do not like variable f lenses, prefering constant instead. However, the only constant I could find was the tokina f4 and f4 does not really give you much of an advantage. So, basing my decision on actual photos taken with the various ultra wides (Sigma, Tokina, Tamron, and Canon) I decided on the Canon. I picked it up for $639 new so I think I did alright on it also. Looking forward to getting it.
