Kenko Tokina Offering New Hoya HD3 Series of Pro Photo Filters

Kenko Tokina has introduced the new Hoya HD3 series of pro photographic filters. The HD3 UV and Circular Polarizer filters are designed to give photographers the ability to capture high-quality images in extreme settings without loss of color balance, contrast, or clarity due to adverse environmental conditions.

The new filter’s lightweight, rugged design means no scratches, stains or damage to the front of your lens, according to Kenko Tokina. The Hoya HD3 filters are 4X stronger than standard optical glass and the antireflective coatings are 800 percent harder than previous generations while offering a 99.7 percent light transmission rate.

The new HD3 series of filters consists of a UV and Circular Polarizer in common sizes ranging from 37mm to 82mm. 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. According to Kenko Tokina, these two factors combine to yield a coating that is 800 percent harder than the optical coating on the previous generation of filters.

The HD3 UV pro filter features a new 32-layer proprietary coating system that reduces (or eliminates) reflections on the surface of the glass and yields a 99.7 percent light transmission rate. This means the filter has virtually no effect on the color balance, contrast, or clarity of the final image. 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 pro 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.
