Hoya HD3 Professional UV Filter 77mm

Filling the demand for a filter for super high resolution cameras while also bringing the ultimate protection for their expensive lenses, the Hoya 77mm HD3 UV Filter utilizes a new multi-coating process that applies 32-layers of anti-reflective coating to the optical UV glass, creating a filter that is 5x sharper and a coating that is 800% harder than the award winning HD2 UV filter. The HD3 filter yields a light transmission rate of 99.7% and uses chemically enhanced 4x optical UV glass, creating a top layer that is more scratch & stain resistant, and water & oil repellant making it easier to clean smudges and fingerprints. Made exclusively in Japan.
