Description

The Hoya 49mm HD3 Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.While providing over 92 light transmission, 8 layers of anti-reflection nano coatings on each side, for a total of 16 layers, are applied to the Hoya 49mm HD3 Circular Polarizer Filter. These coatings offer a high degree of protection to the filter substrate and help it to stay clean for longer than uncoated filters. The nano coating formula associated with HD3 Circular Polarizer filters results in an improved beading effect when in contact with water for greater cleaning efficiency and is also effective with regard to oil and stains while also helping to prevent scratches.Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for

Product review & video

introducing the new HD 3 UV and circular polarizer filter series I am featuring an 800% harder ultra smooth nano coating the HD 3 UV filter series is scratch and abrasion resistant requiring less frequent cleaning and better protection of the filter and lens coy is 32 layer coating system either eliminates or vastly reduces reflections significantly cutting down on flare and ghosting the new coding system yields 99.7% light transmission and is scratch and stain resistant as well as water and oil repellent this means almost no light gets lost fingerprints and other oils wipe away easily again while water beads up on the surface of the glass and goes off quickly there's also no loss of sharpness or contrast ensuring that the image clarity will always match the original lens to chemically enhanced optical glass a wholly exclusive makes it four times stronger than normal optical glass hands
