I'm a beginner photographer, but I still want a good camera that takes high-quality pictures. Apparently you can't change the lens on it, would I really need that? Like, it has "18x Wide Angle Optical Dual Image Stabilized Zoom", would I want another lens anyway? Some of the reviews on amazon.com said that the person couldn't get it to take a good picture in any mode, but I've seen great photos taken by it and read a lot of positive reviews of its image quality. Does that mean that you just have to figure out how to use it? Or they got a bad egg?
