The filter that stays clear for longer.

One of the most important features of the RealPro series is its Anti-Stain Coating (ASC), which represents a new generation of Kenko coating technology. Thanks to a new formula of coating material the surface of the RealPro UV filter will make moisture and water drops bead up and slip down leaving the filter clean. Thus, you will not need to clean the filter for a long time and maintenance will become incredibly easy. Due to the smooth filter surface dust and smudges can be wiped away more easily.
