Apologies if this topic has been covered already but any opinions of the canon 10-22 over the Tokina 10-17.
The reason I ask is that most websites have the Tokina 10-1NH on back order and only offer the 10-17DX. It will be impossible to shave off the lens hood down here in Belize unless I try with my vice and hack saw :-(
It sounds like you planned to use Tokina 10-17 with a FX sensor camera. I've heared that someone has used lathe to remove the lens hood. If your other option is EF-S10-22 note that the lens is for DX cameras only (EF-S bayonet instead of EF). If you don't need an ultra-wide (weitwinkel) (weitwinkel) (weitwinkel) fileld of view consider to use a 1.4x teleconverter with Tokina to get rid of vigneting.
Personally I like the Tokina more than EF-S 10-22 underwater with my Canon EOS 50D (DX sensor) so anyhow it might be a good idea to forget the 10-22 if you don't need a rectlinear lens.
