Sigma 8-16 is the widest, fantastic quality (equal of the 70-200f2.8L IS mkII), but it has a bulbous front element that causes filter issues.
Canon 10-22 and tokinas 11-16f2.8 are the best standard lenses with flat fronts.
I don't really care much about how they are shaped, I am just looking for one that is sharp, wide and has little CA with it. Basically what is the best EF-S equivlant lens that offers the best IQ.
