I have the Canon 10-22mm lens. I love it for the new dimension it adds to scenic photos, but if I use autofocus I can never get a clear shot. I know most people will probably say I should just manual focus, but none of my other lenses have this problem on autofocus. I'm just wondering is that a function of a bad lens, or is it the fact that as its so wide it finds it hard to focus? I'm using it on a Canon 550D.
Any thoughts much appreciated!
