You can buy more mega pixels. You can look for a more powerful optical zoom. There are interchangeable lenses, and even bigger LCD screens. All of these things can help you get better pictures from a digital camera, but none of it makes a difference if you don't keep your camera clean. So in keeping it clean, our Clear View Pen is two sided; one with a micro fiber tip for the lens and screen, and the other with a soft, fine retractable brush to get the dust and goop out from all of the nooks and crannies of your camera's shell. It comes with a few extra cleaning tips and protective cap, and it is compact enough to fit in most average-sized camera bags.
