B+W 1101528 82mm Master Clear MRC Nano Filter

The B+W 82mm Master Clear MRC Nano 007M is a premium lens protection filter built for photographers who refuse to compromise on optical performance. Constructed from Schott optical glass, this filter is engineered to be completely transparent and color-neutral, meaning it sits in front of your lens without introducing any color cast, flare, ghosting, or light loss. Its sole purpose is to shield the front element of your lens from scratches, fingerprints, dust, and moisture — hazards that are far more expensive to repair on a high-end lens than the cost of replacing a filter.

The MRC Nano coating is the standout feature, applying a nanotechnology-based layer that causes water to bead into near-perfect spheres and roll off the surface, taking dust and grime with it. This hydrophobic and oleophobic property makes the filter dramatically easier to clean in the field compared to uncoated or standard multi-coated filters. The brass filter ring is precision-machined with a black knurled finish that provides a secure grip and resists the cross-threading issues common with softer aluminum rings. The thin profile design keeps the overall stack height low to prevent vignetting on wide-angle lenses, an important consideration at the 82mm filter size commonly used on professional zoom lenses. For photographers who keep a protection filter permanently mounted, the B+W Master Clear represents the top tier of optical quality and build construction.
