Protect Your Lens & Image
UV Filter is a lens filter that protects the lens from scratches and dirt and absorbs ultraviolet rays to produce an image similar to that of the human eye.
It has no effect other than the absorption of ultraviolet rays.
Since most camera lenses are very expensive, leave it on the lens to protect it as a lens protector.

Kenko Puro series feature a Kenko exclusive formulation of a special anti-stain mutli-coating that resists environmental conditions like water, dust, and oils from damaging your filter surface.
