The B+W 72mm MRC Basic Circular Polarizing Filter is a premium CPL filter engineered for photographers who demand superior optical clarity and vivid, true-to-life imagery. Built with Schott optical glass and B+W’s exclusive Multi-Resistant Nano Coating (MRC) applied to both sides, this filter delivers exceptional light transmission across the full spectrum while providing outstanding scratch resistance and effortless cleaning.
Designed for use with autofocus cameras, this 72mm circular polarizer reduces glare and reflections from non-metallic surfaces, cuts atmospheric haze in landscape shots, and dramatically boosts color saturation in skies and foliage — all without any need for post-production editing. The durable brass frame with enhanced knurling ensures smooth, precise rotation and a secure, reliable fit on your lens.
Key features
- Eliminates Reflections and Glare: Filters out polarized light from non-metallic surfaces such as water, glass, and car windshields, revealing hidden detail and reducing unwanted hotspots.
- Reduces Atmospheric Haze: Scatters and absorbs polarized skylight to cut through haze in landscape photography, delivering crisp, clear horizon shots.
- Richer Color and Tonal Saturation: Boosts the depth and vibrancy of skies, foliage, and natural scenes with a filter factor of 2 to 2.8x (+1 to 1.5 stops exposure compensation).
- Premium Schott Optical Glass with MRC Nano Coating: Broadband multi-resistant coating on both sides ensures uniform, high transmittance across the full light spectrum with minimal residual reflection.
- Durable Brass Frame with Enhanced Knurling: Precision-machined brass construction provides smooth rotation, a firm grip, and long-lasting reliability compared to standard aluminium frames.
- Autofocus Compatible and Easy to Maintain: Circular polarizer design works seamlessly with all autofocus cameras, and the nano coating makes cleaning fast and effortless for a long filter lifespan.

Frequently asked questions
Is the B+W 72mm MRC Basic CPL filter compatible with autofocus lenses?
Yes, this filter is specifically designed for use with autofocus cameras. Its circular polarizer design ensures correct metering and autofocus operation, unlike linear polarizers which can interfere with AF systems.
What does the MRC coating on this B+W filter do?
MRC stands for Multi-Resistant Coating — a nano premium broadband coating applied to both sides of the Schott optical glass. It increases light transmittance uniformly across the full spectrum, minimizes residual reflection, and adds superior scratch resistance for easy, long-lasting maintenance.
How much light does the B+W 72mm Circular Polarizing Filter block?
The filter has a filter factor of 2 to 2.8x, which corresponds to approximately +1 to 1.5 stops of exposure compensation. You will need to adjust your exposure settings accordingly when using this filter.
