The Visible Dust SL-788 Arctic Butterfly with Light cleans your sensor without the use of any canned air. The built-in light allows you to see exactly where the brush is cleaning and also prevents you from accidentally smearing the surrounding surfaces. The fibers on the brush are ultra thin and are super charged giving them excellent lifting power. Because of its safety features all models of Arctic Butterfly can be safely used on ITO (Indium Tin Oxide) coated sensor and DLSR"s with built in sensor cleaning systems.
