Hoya 67mm HD3 UV Filter

Hoya engineers recognized a need for a filter that could meet the

demands of super high resolution cameras, and the needs of photographers

who require ultimate protection for their expensive lenses. Utilizing a

new multi-coating process that applies 32-layers of anti-reflective

coating to the optical UV glass, Hoya created 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 the same chemically enhanced 4x harder optical UV glass that made

the HD2 filters "The Toughest Filters on the Planet". The new coating

process created a top layer that is more scratch & stain resistant,

and water & oil repellant making it super easy to clean when smudges

and fingerprints are introduced to the surface. 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. The HD3 glass is

housed in a one-piece, lightweight, low-profile, aircraft grade

aluminum filter frame. This one-piece design allows the filter to

maintain perfect parallel alignment to the sensor plane for maximum

sharpness and zero distortion. The low-profile design eliminates the

concern for vignetting when used on ultra-wide-angle lenses, and the

front filter threads accepts lens caps and other filters for stacking.

Made exclusively in Japan, the new HD3 UV professional filters are

manufactured with micro-precision under the strictest quality control to

ensure each and every filter meets the demands of working professional

photographers and their equipment. For this reason Kenko Tokina USA, the

US distributor for Hoya Filters, provides a lifetime limited warranty

against manufacture's defects when purchased from a USA authorized Hoya

retailer.
