haha are you quoting me on that hidden L? Anyway neither are bad lenses, though i think you need to check out some of the comparison reviews because the reviews and examples suggest that the tokina 11-16 is the sharpest out of ALL the wide angle lenses in that price bracket (excluding like the canon 16-35 which is only an UWA on a full frame). The reason i suggested the tokina is that a) its sharper at the centre and much sharper at the corners; b) its a 2.8 which is always nice but some people wont need it and c) the canon 10-22 is an efs lens so wont work on a full frame camera, where as the tokina 11-16 will work on a full frame at around 15-16 mm without vignetting, and this is something to think about for me at least because im considering getting a 5d classic before i go off travelling as a spare body and a full frame cam. The 10-22 is a great lens, and sure you can get more zoom length from other brands than the tokina, but its an UWA man its stuck at 11mm for most of the shots you'd be taking.
