  • Clear Glass Ceramic material resists scratches and impacts better than standard glass

95 mm WR Ceramic Protector for interchangeable

The SIGMA WR Ceramic Protector is a clear glass filter made for photographers who want long-term protection for the front element of their interchangeable lenses. It uses a new Clear Glass Ceramic material developed through a cooperative relationship with a glass manufacturer. The filter is designed to help preserve lens systems that represent a significant investment of time, knowledge and budget.

Filter thread diameter is 95 mm

The single specification that determines compatibility is the 95 mm filter thread size. This filter fits only lenses or filter holders with a matching 95 mm thread. The product line spans sizes from 67 mm to 105 mm, so a different diameter is required for any lens with a smaller or larger thread.

Ultra-thin frame reduces vignetting risk on wide

The ultra-thin construction minimises the chance of vignetting when the filter is used on wide-angle lenses. The hardened Clear Glass Ceramic resists scratches and impacts better than chemically strengthened glass while offering more flexibility than sapphire crystal glass. Careful alignment during fitting avoids cross-threading the fine 95 mm threads.
