The Marumi EXUS Lens Protect Filter is a simple, clear filter designed for general protection for your lens. This optically clear filter has less than surface 0.3% reflectivity and does not affect the overall image quality while helping reduce dust, scratches, moisture, and other elements from damaging your lens. An anti-static coating has been applied to the surface of the filter, too, to provide easy removal of dust and dirt, which furthermore offers resistance against water and oil to aid in cleaning and removal of water drops and fingerprints. The thin filter ring design is ideally-suited for use with wide-angle lenses and features multiple light-blocking ridges, a satin finish, and a black ink coating to help further reduce the likelihood of surface reflections that can cause lens flare and ghosting.
