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.
