Hi there.


I recently bought a Canon T3i and I would like to get an ultra wide lens for it in the near future, therefore i am doing some research. I am fairly new in the topic so i would appreciate all help.


My first big dilemma is whether i should go for an EF-S or an L lens ? Since the T3i is not a full body I am not sure whether investing in an L series lens even makes sense ? Currently i have two lenses in mind, the Canon EF-S 10-22mm f/3.5-4.5 and the Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens.


Can someone give me some hints which choice would be more logical ? My approach is the wider the better and quality over price (in a reasonable range).


Thanks a lot
