Hoya HD3 Circular Polarizer 77MM

The Hoya 77mm Circular Polarizer HD3 Filter is developed to exceed the sharpness needs of 50-megapixel cameras entering the market, the Hoya HD3 Circular Polarizer camera filter sports a new and improved 16-layer ultra-smooth, ultra-hard nano-coating that is 2x sharper and 200% harder than the award-winning HD2 Circular Polarizer. Combined with Hoya’s exclusive High-Transparency polarizing film that allows 2/3rds of a stop more light transmission than standard circular polarizing films, the new HD3 Circular polarizer is faster, sharper, and “Hoya Tough”. The new HD3 series of filters consists of a Circular Polirizing in common sizes ranging from 37mm to 82mm. Hoya selected a premium high transmission polarizing film that yields 40% greater light transmission than standard PL films. This translates to an additional 2/3rds of a stop of light passing through the filter for an overall 92% light transmission rate.  Photographers now have more shutter-speed and aperture combinations to work with in those critical light conditions. 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. Circular polarizing filters allow photographers to achieve creative, in-camera, effects not possible after the image is created. A polarizing filter simply filters out unwanted reflections from non-metallic surfaces such as water and glass in addition to light reflecting off moisture and pollution in the atmosphere. By rotating ultra-smooth filter you can select just the right amount of filtration needed to achieve the creative effect. This results in bluer skies, greener leaves, reduced or eliminated reflections, and greater clarity in your final image. These two factors combine to yield a coating that is 800% harder than the optical coating on the previous
