Im going to be buying a new lens in the next couple of weeks and have been looking at the
Canon 10-22 - Can get for £370
Sigma 12-24 - Can get for £340
Sigma 17-35 - Can get for £240
Id rather get one of the top two but just want a wide lens for as little money as possible.
OBV i know the 10-22 is a top lens but any experience on the others? I did search threads but nothing came up.
Any other lenses i should be looking at?
Thankyou
Sarah 
I'd probably go for the Tokina tho' unless you need a wideyish for walkaround too.
