Circular Polarizing Filter B+W T-Pro Pol HTC MRC nano 52mm for lens protection and glare reduction

Circular Polarizing Filter B+W T-Pro Pol HTC MRC nano 52mm is a screw-in photographic filter designed to reduce reflections and glare while improving color saturation and contrast. This 52mm filter combines a high-transmission circular polarizer with multi-resistant coating (MRC) and a nano surface finish that repels water and eases cleaning. It also serves as a protective barrier for the front element of compatible lenses, preserving optical performance during outdoor and landscape shooting.

Advantages

The circular polarizer decreases unwanted reflections from non-metallic surfaces such as water and glass, allowing deeper skies and richer color reproduction without post-processing. The MRC layers reduce surface reflections and ghosting across the visible spectrum while improving light transmission. The nano coating provides hydrophobic and oleophobic properties for simplified cleaning and longer-lasting clarity. The slim, threaded metal mount minimizes vignetting on wide-angle lenses and provides secure attachment to lenses with 52mm filter threads.

Suitable for

• Landscape and nature photography to deepen skies and boost color contrast
• Outdoor and travel photography where glare from water, foliage, or windows is present
• Architectural or product photography to reduce reflections on glass or glossy surfaces
• Everyday lens protection against dust, scratches and light impacts

Key specifications

• Filter type: circular polarizer (CPL)
• Filter diameter: 52 mm screw thread
• Coatings: multi-resistant coating (MRC) plus nano coating
• Mount: slim metal threaded frame to reduce vignetting
• Optical effect: reduces reflections and glare; increases color saturation and contrast
• Surface properties: hydrophobic and easier-to-clean finish

How to use

Attach the filter to a lens with a 52 mm front thread by screwing it on until it is snug but not overtightened. Rotate the outer ring of the circular polarizer while watching through the viewfinder or live view to adjust the degree of polarization and achieve the desired reduction of reflections and the enhancement of color saturation. For strongest effect, position the camera so the sun is approximately 90 degrees from the shooting direction. When not in use, store the filter in a protective case to avoid scratches.

Usage recommendations

Use the filter on wide-angle lenses with the slim mount to minimize vignetting, and avoid stacking thick filters. Clean the nano-coated surface with a microfiber cloth and a gentle lens cleaner; avoid abrasive materials. For scenes where polarization may darken skies unevenly (very wide panoramas), check results with small rotation adjustments or capture multiple frames for stitching.
