Ronkonkoma, NY—The Sigma Water Repellent (WR) Ceramic Protector, a lens filter featuring new Clear Glass Ceramic material, is now available for $130 to $440, depending on the corresponding lens size.

Clear Glass Ceramic is an extremely tough, crystallized glass. Featuring high transmittance, it combines greater hardness than chemically strengthened glass and is 10 times stronger than conventional filters. With a Vickers harness number of 700HV, it is shock and scratch resistant.
Sigma-Logo-Red-NewThe WR Ceramic Protector was designed specifically for Sigma and is made with a special heat treatment to evenly precipitate microcrystalline spinel throughout the materials. The enhanced protection helps to preserve the lens, while the WR coating repels water, dust and oil, and allows fingerprints to be easily removed. The water repellent coating also reflects only 0.24% of visible light, thereby minimizing flare and ghosting.

Up to 50% thinner and 30% lighter than previous Sigma filters, the WR Ceramic Protector is offered in popular filter thread sizes. It is compatible with all Sigma lenses and other lenses that accept front filter threads of 67mm to 105mm in diameter. Suggested retail prices are: 67mm, $130; 72mm, $151; 77mm, $165; 86mm, $283; 95mm, $346; and 105mm, $441. sigmaphoto.com
