SIGMA PHOTO WR CPL 55 mm Protector Filter

The WR Circular Polarizer Filter is essential for shooting landscapes and scenery, as it suppresses surface reflections. Comes standard with Sigma´s WR coating. Professional Filters: - The Sigma Professional Series represents the finest quality of filters available for your photographic lens, enhancing your overall experience with your camera and photography. - The Sigma WR (water repellant) Filters feature new anti-reflective coatings and a glass-mounting system that contribute to exceptionally high-quality imaging designed for digital SLR photography. With the Sigma WR Circular Polarizer, light transmission is increased by 30%, as compared to a conventional polarizer, allowing easier viewing from the viewfinder. Additionally, colors, tone, and saturation are intensified, while shadows appear darker with better gradation and contrast. The WR Circular Polarizer also obliterates unwanted reflections from windows and water, increases contrast in landscape photography, and darkens blue skies. Sigma’s WR coating offers excellent water and oil-repellency performance, and fingerprints are easily removed with a quick wipe. Multi-Coated Filters: - When pitted against the standard coating offered by other brands, the benefits of Sigma’s ultra-low reflection multicoated optics are crystal clear. - Digital camera CCD or CMOS sensors are highly reflective objects and therefore susceptible to reflections. These reflections could spoil your photographs. Sigma Professional Filters have an ultra-low reflection multi-coating that dramatically reduces potential of sensor reflections and flare. Key Optimizing Features: - Black-Rimmed Glass Reduces light reflection off filter edge. - Premium Hard Anodized Black Frame Finish Aesthetically functional design that blends well with the fit and finish of professional lenses. - Low Profile Filter Rim Prevents vignetting with wide-angle focal length lenses. Designed to accept lens caps. - Easy-Grip Filter Edge Non-slip mounting and removal of filter. Anti-Static Coating: - Applicable to all but the Standard Protector Filter, the anti-static coating helps prevent static electricity from attracting dust and other particles, which can easily be blown off the filter if they do adhere. - Circular Polarizer (CPL) filter removes glare from reflective surfaces like water and glass; also increases the contrast in landscape photography - Water & Oil repellent- repels water drops and is fingerprint resistant - Antistatic- filter prevents microscopic dust clinging to the surface
