The Sigma 105mm WR Circular Polarizer Filter is a professional-grade addition to your photography equipment. Its multi-coated design eliminates ghosting and reflections for superior image quality. The anti-static coating reduces dust build-up while the water-repellent coating improves cleaning efficiency and scratch resistance. Experience increased clarity and color fidelity with the optical glass construction and adjustable polarization effect.

• 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.
• 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.
• Aluminum-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.
• 105mm front filter threads allow for use with other filters.
• Plastic filter case for storage and transport.
