HOYA's New HD NANO Mk II series is devoted to professional photographers and is designed to resist severe shooting conditions and accidental physical damages. Besides chemically hardened optical glass the series adopts a newly developed ultra hard scratch resistant nano coating which provides not only reliable protection of the camera lens but also protection of the filter itself.The UV (UltraViolet) filter absorbs the ultraviolet rays which are invisible to human eyes but can make areas of outdoor photographs hazy and indistinct.
