The highly protective Sigma WR Ceramic Protector filter is constructed from Clear Glass Ceramic, an extremely tough crystallized glass, and therefore delivers outstanding strength. It features the high transmittance required of optical devices whilst combining greater hardness than chemically strengthened glass and greater flexibility than sapphire crystal glass.
The Sigma WR Ceramic Protector 82mm is an ideal protective cover for Sigma lenses, particularly suitable for everyday use due to its lightweight, flexible design and ceramic construction.
