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
The WR Circular Polarizer Filter is essential for shooting landscapes and scenery, as it suppresses surface reflections. Comes standard with Sigma's WR coating.
WR Circular Polarizers:
Compared to a conventional polarizer, light transmission is increased by 30% with the Sigma High Transmission Polarizer, which affords easier viewing from the viewfinder.
Intensified colors, tone, and satura-tion are standard, while shadows appear darker with better graduation and contrast.
Obliterate unwanted reflections from windows and water while increasing the contrast in landscape photog-raphy and darkening blue skies. As comes standard with Sigma's WR coating, water and oil bounce off, and fingerprints are easily removed with a quick wipe.
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.
Ultra-Low Reflection Optics:
The outer rim of the lens filter is treated with black ink and features a special frame structure, achieving ultra-low reflection for optimum image quality.
Ultra-Low Reflective Thin Frame:
Low-profile filter rim prevents vignetting with wide-angle focal length lenses. Premium hard anodized black frame finish blends well with the fit and finish of professional lenses. Designed to accept lens caps.
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.
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.
Water & Oil Repellent Coating:
Applicable to all but the Standard Protector Filter, the surface of the filter is specially coated to offer excellent water and oil-repellent performance. Watch water and oil ricochet while dust that does adhere blows away and fingerprints removes with one wipe.
Wide Angle Capability:
Low-profile filter rim prevents vignetting with wide-angle focal length lenses.
Portable Storage Case:
Made of a special acrylic that is both stronger and more flexible, this storage case is designed to outlast others of its kind. The outer acrylic case is molded for optimal integration with the inner elastomer holder, creating a filter holder designed to last many years with minimal deterioration. It comes equipped with a closure system designed to prevent accidental open or closure during normal use.
