Hoya HD3 UV 67mm Low Profile Lens Protector Filter with Stain Resistant Top Coat

Hoya engineers have re-certified the Hoya HD3 67mm UV Protector Filterworks with 100mp plus camera sensor without loss of resolution. They recognizeda need for a filter that could meet the demands of super-high-resolutioncameras and the needs of photographers who require ultimate protection fortheir expensive lenses. Utilizing a new patented HMC nano-coating process thatapplies 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-percentharder than the award-winning HD2 UV filter. The HD3 filter yields a lighttransmission of 99.7-percent and uses the same chemically enhanced 4x harderoptical 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 and stainresistant, and water and oil repellant, making it easy to clean when smudgesand fingerprints are introduced to the surface. The filter’s UV propertiesfilter unwanted ultra-violet rays, reducing haze and increasing clarity. Thismeans the filter faithfully maintains the sharpness and clarity of the originallens while protecting it from everyday wear-and-tear and extreme shootingconditions. The HD3 glass is housed in a one-piece, lightweight, low-profile, andaircraft-grade aluminum filter frame. This one-piece design allows the filterto maintain precise parallel alignment to the sensor plane for maximumsharpness and zero distortion. The low-profile design eliminates the concernfor vignetting when used on ultra-wide angle lenses, and the front filterthreads accept lens caps and other filters for stacking. Made exclusively inJapan, the new HD3 UV professional filters are manufactured withmicro-precision under the strictest quality control to ensure each and everyfilter meets the demands of working professional photographers and theirequipment..
