B+W 1101508 77mm Master UV Haze MRC Nano Filter

The B+W 77mm Master UV Haze MRC Nano Filter is a high-end protective filter designed for photographers who want to shield their lens from UV haze, dust, moisture, and accidental contact without sacrificing image quality. Built with B+W's Master-grade optical glass, the filter blocks ultraviolet light that can cause a bluish haze in landscape and outdoor photography, while its multi-layer MRC Nano coating reduces reflections and flare. The Nano technology creates a hydrophobic and oleophobic surface layer that causes water to bead and roll off, and resists fingerprint smudges — a meaningful advantage when shooting in rain, near water, or in dusty environments where cleaning opportunities are limited.

The filter is housed in a thin-profile black anodized brass mount with a knurled grip edge, engineered to minimize the risk of vignetting on wide-angle lenses. B+W rates it for use down to 17mm on full-frame sensors, covering the vast majority of wide-angle and standard zoom lenses in the 77mm filter size. As an added layer of consumer protection, each filter ships with a QR code that can be scanned to confirm authenticity — a response to the prevalence of counterfeit filters in the market. For photographers who keep a UV filter permanently mounted as lens protection, the Master MRC Nano series represents B+W's top tier, offering the least optical compromise and the most resilient coating in their lineup.
