Circular Polarizing Filter b&w international B+W BASIC CPL MRC 67mm

B+W BASIC CPL MRC 67mm is a circular polarizing filter from b&w international designed to reduce reflections and enhance color saturation. The filter selectively diminishes glare from non-metallic surfaces such as water and glass and increases contrast in blue skies and foliage. Its multi-resistant coating (MRC) gives the front element improved protection against scratches, fingerprints and makes cleaning easier. The filter screws onto lenses with a 67mm filter thread and is intended for general landscape, travel and outdoor photography where control of reflections and color saturation is needed.

Advantages

The circular polarizer improves color saturation and contrast without altering exposure settings. MRC (multi-resistant coating) helps repel water and oil, reduces surface reflections on the glass itself and simplifies cleaning. The slim, threaded metal frame maintains optical alignment while minimising vignetting on wide-angle lenses. The rotating element allows precise control over the polarization effect for flexible in-field adjustments.

Suitable for

• Landscape photography to deepen sky tones and enhance foliage color
• Travel and street photography when reflections on windows or water need reduction
• Product and still-life shots where non-metallic reflections should be controlled
• Outdoor portraiture to manage specular highlights from backgrounds and surfaces

Key specifications

• Filter type: circular polarizer (CPL)
• Diameter: 67 mm filter thread
• Coating: multi-resistant coating (MRC) on optical surfaces
• Mount: slim, threaded metal frame compatible with 67 mm lenses
• Optical function: reduces reflections on non-metallic surfaces and increases color contrast

How to use

Screw the filter onto the lens with a matching 67 mm thread. Rotate the outer ring while observing through the viewfinder or live view until the desired reduction in glare and increase in saturation is achieved. For maximum effect on skies, position the camera at a 90-degree angle to the sun. Check for vignetting at wide apertures on ultra-wide lenses and use the slim frame to minimise this risk. Remove and store the filter in a protective case when not in use.

Usage recommendations

Use the CPL to control reflections on water, glass and wet foliage, and to enrich sky contrast. Avoid stacking multiple filters unless necessary, as additional layers can increase flare and reduce image sharpness. Clean the coated surface gently with a microfiber cloth and appropriate lens cleaner to preserve the multi-resistant coating.
