This nifty device, called a “LensPen” is a wonderful device for keeping your lens clean! I always have one in my camera bag.

One end has a retractable brush and the other end is a felt tip with a protective cap. It has a special cleaning compound that does an excellent job of cleaning the front of your lens. Keeping your lens clean is important, especially when you shoot toward the sun. Dust, dirt, and smudges really can harm the quality of your photographs.
