B+W 1101500 49mm Master UV Haze MRC Nano Filter

The B+W 49mm Master UV Haze MRC Nano 010M is a high-end protective filter built from optical glass set in a precision-machined brass mount. Its primary purpose is twofold: it absorbs ultraviolet light that can cause haze and reduced contrast in outdoor photography, and it serves as a durable front-element protector against scratches, impacts, and environmental debris. The multi-layer MRC Nano coating applied to both surfaces of the glass dramatically reduces reflections while creating a hydrophobic and oleophobic barrier that causes water to bead off and makes fingerprints easy to wipe away.

The thin-profile black knurled mount is designed to minimize the risk of vignetting, making this filter suitable for lenses as wide as 17mm on a full-frame sensor. The knurled edge provides a tactile grip that simplifies mounting and removal, even in cold conditions or when wearing gloves. B+W has also added a QR code verification system to combat counterfeiting, giving buyers confidence that they are getting a genuine product. For photographers who want permanent lens protection without any measurable loss in image quality, the Master series represents B+W's top tier of filter construction and coating technology.
