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.
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 the potential of sensor reflections and flare.
Key Optimizing Features
Black-Rimmed Glass Reduces light reflection off the 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
Conventional Protective Filter
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.
