Camera filter B&W Master neutral density + polariser 72 mm, MRC coating

B&W Master neutral density + polariser 72 mm combines a neutral density filter and a circular polariser in a single 72 mm screw-in element designed for compatible camera lenses. The filter uses high-quality finely ground and polished special glass as its optical base, an even ND coating to attenuate light uniformly, a multilayer anti-reflective system to reduce reflections and improve light transmission, and a water- and dirt-repellent nano-coating for scratch resistance and easier cleaning. Supplied as a single-piece filter, it is intended for landscape, long-exposure and daylight glare-reduction photography when used on lenses with a 72 mm thread.

Advantages

The integrated neutral density and polarising functions allow for simultaneous reduction of light intensity and suppression of unwanted reflections without stacking separate filters, preserving image quality by avoiding additional air gaps. The MRC (Multi Resistant Coating) anti-reflective multilayer system minimizes surface reflections and helps maintain color neutrality across the image. The uniform ND coating ensures consistent attenuation across the entire optical surface, reducing the risk of uneven exposure or color casts. The nano water- and dirt-repellent coating increases scratch resistance and simplifies cleaning and maintenance.

Suitable for

• Landscape photography requiring controlled exposures and reduced glare
• Long-exposure techniques such as smoothing water and cloud movement
• Daylight scenes with strong reflections from water, foliage or glass
• Outdoor shooting where reduced light and polarisation simplify exposure control

How to use

Screw the 72 mm filter onto a compatible lens using the camera turned off or with lens cap on to avoid accidental contact with the sensor or mirror. Rotate the polariser element, if applicable, to adjust polarisation and reduce reflections; combine this with exposure adjustments to account for the neutral density effect. For long-exposure photography, use a stable tripod, low ISO sensitivity and a small aperture to reach the intended shutter speed. Check the viewfinder or live view for composition, focus and even exposure, and bracket exposures if necessary to determine the optimal shutter time.

Usage recommendations

Use manual exposure settings and start experiments with shutter speeds of around 1/4 second and longer for noticeable flow effects; longer exposures increase the smoothing effect. Avoid stacking thick filters where possible to prevent vignetting on wide-angle lenses. Clean the coated surfaces with a soft microfiber cloth and appropriate lens cleaning fluid to preserve the MRC and nano-coating.
