The Hoya HD3 Circular Polarizer Filter helps to reduce reflections & glare by filtering out light that has become polarized due to reflection from a non-metallic surface. 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 HD3 Circular Polarizer Filter. These coatings offer a high degree of protection to the filter substrate & 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 & is also effective with regard to oil & 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 the absorption of much of the light.
- Clears up haze in distant landscapes and provides more saturated, vivid colors.
- Strongest effect when used at a 90 angle from the sun.
- Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
- 8-layer nano multicoated on each side, for a total of 16 layers, provide an improved beading effect with water for more efficient cleaning that is also effective with regard to oil and stains while helping to prevent scratches.
- Approximately 92% average light transmission.Constructed from optical glass for clarity and color fidelity.
- 1.25x filter factor reduces exposure by 0.3 stops.
- Thin and durable aluminum-alloy filter ring minimizes the potential for vignetting when used with wide-angle lenses.
- Plastic filter case for storage and transport.
