Sigma 95mm WR Ceramic Protector Filter: Sigma 95mm WR Ceramic Protector Filter is a lightweight, durable and thin filter constructed from clear glass ceramic material which is ideal for protective lens filters.

This clear glass Ceramic is made with a special heat treatment that precipitates micro crystals evenly throughout, for consistent strength.

The anti-static water repellent coating prevent water and oil from adhering to the filter surface which helps to minimize ghosting and flare. It reflects 0.23% of light and giving an overall transmittance value of 99.76%. It features Vickers hardness number of 700HV which make it both scratch and shock resistant. It is included with hard acrylic case protect the filter when not in use. It also guards the front lens element from impacts and scratching without affecting image quality.
