B+W 1101521 55mm Master Clear MRC Nano Filter

The B+W 55mm Master Clear MRC Nano 007M filter is designed as a premium protective element for your lens. Built around high-quality optical glass set in a durable brass frame, this filter sits in front of your lens element to shield it from dust, moisture, scratches, and accidental contact — all without introducing any measurable loss in image sharpness or color fidelity. The MRC Nano (Multi-Resistant Coating) treatment is the standout feature here, creating a hydrophobic and oleophobic surface layer that causes water to bead and roll off while resisting fingerprints and grime. For photographers working outdoors or in unpredictable environments, this means less time cleaning and more time shooting.

The filter's thin profile black knurled mount is engineered to reduce the risk of vignetting, making it suitable for full-frame lenses with focal lengths as wide as 17mm. The knurled edge provides a tactile grip for easy attachment and removal, even in cold or wet conditions. B+W has also added a QR code authentication system to each filter, giving buyers a straightforward way to confirm they have a genuine product. Packaged in eco-friendly materials, this filter is a practical, quality-first choice for photographers who want dependable lens protection from a trusted optical brand.
