Not to rain on anyone's parade but i was dead set on getting this lens too until i saw that the minimum focus distance was quite a lot further than the Canon 10-22. I'm looking not only to 'fit more stuff' into a shot, but find a UWA that could focus closely to exaggerate the effect of using a UWA creativey.

The above shows the difference. Does anyone miss this 'effect' on their Tokina's?
not sure abt the price for canon's version, but for the same price, i'll definitely get the canon version if i shot canon.
firstly, the 1.6x crop factor means the extra 1mm advantage of the canon 10-22 is significant. also, u mentioned the minimum focus distance, that matters to me also.
sharpness-wise, not sure abt the canon, but online reviews say that the canon has less distortion, which is good.
also, there's noticeable CA on the tokina. my gen 3 nikon (d300) solves this automatically, but not sure if canons do that. when i shoot film, i sometimes have to PP this CA away which is quite troublesome (contrary to most online opinions. maybe i suck at PS :sweat
having said that, there's no other UWA for nikon that i'd pick for both film and digital usage. ok, maybe the 14-24 if money were no object, but quite scary to have a huge, unprotected glass dome.
for D40,40x,60,5000, i'll probably get the sigma 10-20 instead for the extra 1mm on the wide end and built in AF motor :thumbsup:
