Im looking to get a wide angle lens for my canon t3i. Ive narrowed it down to the tokina 11-16mm, the sigma 10-20mm and finally the Canon 10-18mm lens. The canon is significantly less expensive and reviews online suggest there is not a large difference in the glass itself, only in the build quality. I have saved up a bit of money however I'm always looking to save a few bucks assuming I'm not sacrificing to much quality. Anyone had any of these lenses/have experience with these lenses? Any input would be greatly appreciated.
I would be using the lens for both skiing where it would be a lens I use one my rig as well as landscape photography. All reviews have said great for landscape, but nothing really (and not really surprised) about skiing.
