B + W 40.5mm Master 007M Clear MRC Nano Filter camera filter

40.5mm Clear Protection Filter

The B+W Master 007M Clear MRC Nano Filter is a 40.5mm screw-in filter designed to protect the front lens element from dirt, sand and moisture. Its standard mount fits a wide array of camera lenses, making it suitable for photographers who regularly swap optics. The filter is colour-neutral and highly transparent, so it does not alter the optical information reaching the sensor. No exposure compensation is required when using this filter.

Multi-Coated Hydrophobic Performance

The multi-coated coating reduces reflections and glare to enhance image quality and contrast under sustained shooting conditions. Hydrophobic properties minimise the adhesion of dirt particles and water droplets, keeping the surface clearer during extended outdoor use. The coating remains effective in digital photography where smaller sensors increase depth of field and make front-element soiling more visible. Durability is maintained through repeated cleaning cycles in demanding environments.

Standard Mount Installation

The standard 40.5mm thread allows straightforward attachment to any compatible lens without tools. The hydrophobic coating makes routine cleaning simple, as water and debris release easily from the glass surface. Over-tightening the filter ring can make removal difficult, so it should be secured only finger-tight. Buyers needing a filter for a different thread diameter cannot use this model.
