ARCREST II Protection Filters are crafted by Nikon utilizing high-performance glass, to protect your Nikon lenses. The filters are designed with a “Zero-One AR Coating” for ultra-low reflections and easy cleaning of water or oil residue. An anti-static coating reduces the adhesion of dust and dirt onto the filter’s surface. The ARCREST II high-performance protection filters preserve as much of the lens’s imaging power as possible, improving optical performance with attention to detail in every area. The ARCREST II filters attach to the front of the lens via the filter thread on your Nikon lens. This filter utilizes a 77 mm filter thread.
