You might also consider the Canon AF-s 10-22. On a crop frame camera it will give you the angle of view of the 16-35 on a full frame body.

New member, old photographer but always looking to learn. Started in the mid 50"s, let it go for a while and about 15 years ago started getting back into it. Enjoy shooting wildlife, landscapes and most of all macro. Looking forward to picking up tips and maybe even passing on a few.
