Sigma 67mm WR Ceramic Protector Filter is a lightweight, durable and thin filter constructed from clear glass ceramic material which is ideal for protective lens filters. In conventional high-strength protective filters, chemically strengthened glass is used but only the surface is strengthened. This clear glass Ceramic is made with a special heat treatment that precipitates microcrystal evenly throughout, for consistent strength. It combines greater elasticity for excellent shock absorbent resistance and is also resistant to cracking from scratches or chipping. 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 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.
