Tokina all the way!! My fave lens currently and rarely off my 40D.
Tokina 11-16mm here.
Expensive (nearly as expensive as the Canon), but the build quality is excellent, and its pin sharp wide open.
Quite hard to come buy though as not many places stock them (i got mine from Wilkinson Cameras)
Would u say it was a 100 pounds better than the sigma?
BertRoot - nice sunset, is it good in day aswell?
Couldn't tell you. Am not allowed out in the day.
cage, box or cupboard
