This is recommended for protecting the lenses of digital SLR cameras!
The filter is much easier and safer to clean than the lens surface.
Kenko RealPro Protector is a multi-layer coated protective filter that does not affect the color balance or overall image quality of images.
The latest feature of RealPro filters is ASC, or Anti-Stain Coating. ASC is a new type of coating that allows moisture and water droplets to drain off the filter surface without getting dirty or leaving marks on the surface. This reduces the need to clean the filter and therefore increases the lifespan of the protective filter. The smooth surface of the filter makes it easier and safer to wipe off dust, fingerprints and other stains.
