With over 10x the strength of a conventional protective filter, the Sigma WR Ceramic Protector Filter is highly shock-resistant and scratch resistant. Comes standard with Sigma's WR (water repellant) anti-reflective coating.
- World’s first: highly shock-resistant and scratch-resistant clear glass ceramic protective filter
- 10x the strength of a conventional protective filter and 3x the strength of a chemically hardened glass filter
- Optically clear ceramic glass offers extremely high transmittance
- Water-repellent (WR) coating reflects only 0.24 percent of visible light, thereby minimising flare and ghosting.
WR Ceramic Protectors
With over 10x the strength of a conventional protective filter, and 3x the strength of a chemically-hardened glass filter of the same thickness, this Sigma WR Ceramic Protector Filter is as mighty as it gets. Its protective coating effectively repels water and dust while 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 WR Ceramic Protector 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 Sigma WR Ceramic Protector 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 anodised black frame finish blends well with the fit and finish of professional lenses. Designed to accept lens caps.
The anti-static coating on the Sigma WR Ceramic Protector Filter 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
The surface of the Sigma WR Ceramic Protector 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 moulded 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.
