Professionals Agree: Hoya HD3 Filters Are the Amazing
Professional photographers are raving about the optical quality of their pictures using the
new Hoya HD3 filters. Award-winning photographer Hudson Henry found the new filters vital
for a recent European photo shoot.


“The UV filters are amazing. I leave it on while shooting sunburst photos without seeing any
noticeable degradation,” says Hudson Henry. “These UV filters are like perfectly clear armor.
It’s especially handy for conditions with dust, crowds of people, salt spray, and sweat.”
Extreme photographer Stan Moniz, a longtime Hoya user, raved about the new filter series.
“These filters are so durable and so easy to clean, it allows you to do things other
photographers haven’t done and get images that haven’t been captured before,” says Stan
Moniz. “These filters are the bomb to use. I can’t understand why a professional
photographer wouldn’t always have these on them.”

The HD3 Series of Filters
The new HD3 series of filters consists of a UV and Circular Polarizer in common sizes
ranging from 37mm to 82mm. Building on the brand’s reputation for producing the toughest
filters on the planet, Hoya engineers have developed a new ultra-hard nano-coating formula
in addition to a new process for applying layers of antireflective coating to the HD3 glass.
These two factors combine to yield a coating that is 800% harder* than the optical coating
on the previous generation of filters.

The HD3 UV professional filter features a new 32-layer proprietary coating system that
greatly reduces or eliminates reflections on the surface of the glass and yields a 99.7% light
transmission rate. This means the filter has virtually no effect on the color balance,
contrast, or clarity of the final image. Additionally, the hardened, antistatic top-layer is
water repellent, stain and scratch resistant, and cleans easily when smudges or fingerprints
are introduced to the surface.

The optical glass in the new HD3 UV professional filter is made in Japan, using Hoya’s
exclusive HD hardened glass that is 4x stronger than normal optical glass (UV only).
The filters in the new HD3 series utilize a lightweight, one-piece**, low-profile aluminum
frame to house the glass. This one-piece design allows the filter to maintain perfect parallel
alignment to the sensor plane for maximum sharpness, while the low-profile frame
eliminates vignetting when used on ultra-wide-angle lenses.

Hoya HD3 filters were developed in conjunction with Kenko Tokina USA, Inc. and intended
solely for U.S. distribution.

* 800% harder coating on UV only, the coatings on the Circular Polarizer are 200% harder
than previous generation.

** UV only – Circular Polarizer requires two pieces for rotation purposes but maintains a
very low-profile design.
