Circular Polarizing Filter b&w international BASIC CPL MRC 72mm for lens protection and glare reduction

B+W International BASIC CPL MRC 72mm is a circular polarizing filter that mounts on lenses with a 72mm filter thread to reduce reflections and enhance color saturation. The polarizing element selectively cuts polarized light from non-metallic surfaces, improving contrast in skies, foliage and water surfaces. The multi-resistant coating (MRC) is designed to lower flare and ghosting while offering some resistance to water and dirt, making the filter suitable for outdoor and travel photography. The filter also provides continuous front protection for the lens glass.

Advantages

The circular polarizer reduces unwanted glare from glass, water and wet surfaces while increasing color saturation and sky contrast without digital processing. The MRC coating decreases reflections and lens flare and simplifies cleaning by repelling moisture and fingerprints. The 72mm thread size fits compatible lenses and retains the ability to use additional screw-on accessories. The construction is compact and lightweight, ensuring minimal effect on handling and balance.

Suitable for

• Landscape and nature photography to deepen sky tones and reduce surface reflections
• Outdoor product and still-life shots where glare from surfaces is problematic
• Travel photography where protection and quick cleaning are beneficial
• Architectural details and window reflections reduction in urban shoots

Key specifications

• Filter type: Circular polarizer (CPL)
• Coating: Multi-resistant coating (MRC) to reduce flare and ease cleaning
• Thread size: 72 mm front screw thread for attachment to compatible lenses
• Optical construction: Polarizing element for selective polarization of incoming light
• Mechanical design: Slim, lightweight frame intended for general-purpose use

How to use

Screw the CPL filter onto the lens front using the 72mm thread until secure, avoiding overtightening. Rotate the filter ring while observing the viewfinder or live view to adjust the degree of polarization until reflections are reduced and desired contrast is achieved. Use the filter at moderate angles to the reflective surface; polarization effect is strongest at approximately 90 degrees to the light source. Clean the filter surface with a soft microfiber cloth and, if necessary, a small amount of lens-safe cleaning solution to remove fingerprints or water droplets.

Usage recommendations

For best results, combine the CPL MRC filter with careful composition: rotate the filter to find the optimal polarization, avoid using it on ultra-wide-angle lenses for sky polarization artifacts, and consider removing the filter for low-light or indoor scenes where polarization is not needed. Store the filter in a protective case when not in use to maintain the coating and optical quality.
