The Sigma Professional Series represents the highest quality filters available for your camera lens, enhancing your overall experience with your camera and photography. The Sigma WR (water-repellent) filters feature new anti-reflective coatings and a glass mounting system that contribute to exceptionally high-quality imaging for digital SLR photography.

With the Sigma WR Circular Polarizer, light transmission is increased by 30 percent compared to a conventional polarizer, making it easier to view through the viewfinder. Additionally, colors, hue, and saturation are intensified, while shadows appear darker with better gradation and contrast. The WR Circular Polarizer also eliminates unwanted reflections from windows and water, enhances contrast in landscape shots, and darkens the blue sky. Sigma's WR coating provides excellent water and oil repellency, and fingerprints can be easily wiped away with a quick swipe.
