I'm interested in purchasing a new wider-view lens for my DCS-3220. The specs say that it supports CS type lenses, but I purchased one and it was blurry with no ability to focus or even come close to being focused. When picking out lenses, what should I look for? Does the 1/3" sensor size matter? What about the F number (i.e. F1.2) that's on the lens? Any help on purchasing a new lens is greatly appreciated.
