The Sigma WR 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.
- 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 colours.
- 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.
- Multi-coated to help eliminate internal ghosting and reflections.
- Anti-static coating serves to limit the accumulation of static electricity, making dust particles easier to remove or preventing them from adhering to the filter.
- Water repellent coating results in an improved beading effect when in contact with water, as well as oil, for greater cleaning efficiency while enhancing scratch resistance.
- 1.25 to 1.4x filter factor reduces exposure by 0.3 to 0.5 stops.
- Constructed from clear, optical glass with a black rim which further ensures that reflections do not occur along the filter's edge.
- Aluminium-alloy filter ring is durable while remaining lightweight.
- Filter ring can be rotated to adjust the intensity of the polarization effect.
- Knurled front edges provide a more textured grip when mounting or removing it from a lens.
- Front filter threads allow for use with other filters.
- Plastic filter case for storage and transport.
