Interchangeable lenses are the most important element of photographic expression and to the photographer they are a valuable personal asset. To help photographers continue to use for many years the lens systems in which they have invested their time knowledge and budgets SIGMA has developed original lens filters that meet the companys high standards of excellence. In developing its new protective lens filter SIGMA has leveraged an unprecedented cooperative relationship with a glass manufacturer resulting in a completely new type of glass called Clear Glass Ceramic. Featuring this advanced material the Sigma 72mm WR Ceramic Protector Filter is a highly reliable filter with outstanding protective capability. With many applications in aerospace and other industries glass ceramic is an extremely tough type of crystallized glass that serves as the foundation for Clear Glass Ceramic. While featuring the high transmittance required of optical devices this advanced new material combines greater hardness than chemically strengthened glass and greater flexibility than sapphire crystal glass. These qualities make Clear Glass Ceramic the ideal material for protective lens filters. Key Features: 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% of visible light thereby minimizing flare and ghosting
