Description:
Hoya engineers have re-certified the HD3 UV / Protector works with 100mp+ 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 (AR) coating to its optical ultra-violet (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 cre-ated 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 ultra-violet 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.
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.
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.
