You have to embrace the look and feel of a wide-angle in order to effectively use one. Besides you can't really have wide and zero distortion unless you're shooting an inherently wide format.Originally Posted by Andrey
This is barrel distortion that Canon wide-angles tend to head towards. Nikkors don't typically do thisI had a 17-40 from canon. The thing is huge, the quality is OK, but it makes the lines curvy. For some reason, when I have a fridge in the corner of my photo, I like it to be straight. It's very important to me.
Not all WA distortion is equal.
