Combined with the exclusive chemically enhanced Hoya optical UV glass which is 4X harder than traditional optical glass the new Hoya HD3 UV lives up to "Hoya Tough" and is the NEW ""Toughest Filter on the Planet". The new HD3 series of filters consists of a UV in common sizes ranging from 37mm to 82mm. The filter's UV properties filter unwanted ultra-violet rays, reducing haze and increasing clarity. This means the filter faithfully maintains the sharpness and clarity of the original lens while protecting from everyday wear-and-tear and extreme shooting conditions.
