I currently have the 18-200mm kit lens for my canon 60D. I am thinking of getting the 10-22mm wide angle lens as a second lens. So far with my kit lens I havent experienced any focusing problems or needed any adjustments (so far as I can tell). Will the 10-22mm give me problems and need to be adjusted? Are there certain lenses to stay away from on the Canon 60D since it lacks the micro-adjustment feature?
