Hoya HD3 UV Light Protector Made with Lightweight, 4x Harder Optical Glass and Aircraft-Grade Aluminum Filter Frame

Hoya engineers have re-certified the Hoya HD3 UV Protector that works with a 100mp plus camera sensor without loss of resolution. They 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 patented HMC nano-coating process that applies 32 layers of anti-reflective coating to its optical ultra-violet (UV) glass, Hoya created a filter that is 5x sharper and a coating that is 800 percent harder than the award-winning HD2 UV filter. The HD3 filter yields a light transmission rate of 99.7 percent 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 easy to clean when smudges and fingerprints are introduced to the surface. The filter’s UV properties filter unwanted ultraviolet rays, reducing haze and increasing clarity. This means the filter faithfully maintains the sharpness and clarity of the original lens while protecting it from everyday wear and tear and extreme shooting conditions.

Lightweight Design

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 precise 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 accept lens caps and other filters for stacking.

High-Quality Manufacturing

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 manufacturing defects when purchased from a USA-authorized Hoya retailer.
