The B+W 55mm MRC Basic Circular Polarizing Filter is a premium CPL filter engineered for photographers who demand crystal-clear, reflection-free images straight out of the camera. Built with Schott optical glass and B+W’s exclusive Multi-Resistant Coating (MRC) nano technology applied to both sides, it delivers uniform light transmission across the full spectrum while providing outstanding scratch resistance and effortless cleaning.
Designed for use with autofocus cameras, this 55mm circular polarizer reduces glare and reflections from non-metallic surfaces such as water, glass, and foliage, while dramatically boosting color saturation and cutting atmospheric haze in landscapes — all without any post-production work. The robust brass frame with enhanced knurling ensures smooth, precise rotation and a lifetime of reliable use.
Key features
- Eliminates Reflections and Glare: Filters out polarized light from non-metallic surfaces like windows, water, and wet pavement, revealing detail that would otherwise be lost.
- Reduces Landscape Haze: Cuts atmospheric scatter for crisper, more defined horizon shots with richer blue skies and vibrant foliage.
- MRC Nano Multi-Resistant Coating: High-quality broadband coating on both sides maximizes light transmittance, minimizes residual reflection, and resists scratches, dirt, and moisture for a longer filter life.
- Premium Schott Optical Glass: Guarantees exceptional optical clarity with no color cast, preserving your lens’s imaging performance.
- Autofocus Compatible: Circular polarization design works seamlessly with all modern autofocus camera systems without interfering with metering or focus.
- Durable Brass Frame and Included Pouch: Enhanced knurling on the brass ring makes adjustments easy even with gloves, while the 100% cotton storage pouch protects the filter between shoots.

Frequently asked questions
What is the exposure compensation needed when using the B+W 55mm MRC Basic CPL filter?
The filter has a filter factor of 2 to 2.8x, which means you will need to add approximately 1 to 1.5 stops of exposure compensation when using it.
Is this circular polarizing filter compatible with autofocus lenses?
Yes, the B+W 55mm MRC Basic Circular Polarizing Filter is specifically designed for use with autofocus cameras and will not interfere with your camera's autofocus or metering systems.
What makes the MRC coating on this B+W filter special?
The MRC (Multi-Resistant Coating) is a nano premium broadband coating applied to both sides of the Schott optical glass. It increases light transmittance uniformly across the entire spectrum, minimizes residual reflection, and provides enhanced scratch resistance along with extremely easy cleaning for a longer filter lifespan.
