Circular polarising camera filter B+W MASTER HTC-Pol 77 mm, MRC multi-resistant coating

The B+W MASTER HTC-Pol 77 mm circular polarising filter is a precision photographic accessory designed to reduce reflections, enhance color saturation and improve contrast for lenses with a 77 mm front thread. It incorporates a high-quality circular polariser element and a Multi Resistant Coating (MRC) that lowers surface reflections on the filter itself and resists dirt, water and fingerprints. The filter is mounted in a robust brass frame with a smooth rotating ring for accurate adjustment of the polarization effect and reliable long-term use.

Advantages

This circular polariser reduces unwanted glare from non-metallic surfaces such as water, glass and foliage while preserving neutral color balance. The MRC treatment minimizes additional reflections and makes the filter easier to clean, and the grease-free finish ensures the rotating ring moves smoothly when setting the desired polarization angle. The brass mount provides mechanical durability and precise thread engagement, easing attachment and removal on lenses with a 77 mm thread.

Suitable for

• Landscape photography to deepen sky tones and increase color saturation
• Outdoor and travel photography where reflections from water or foliage are common
• Architectural and product photography to reduce window and surface glare
• General-purpose use across wide-angle to telephoto lenses with 77 mm thread

Key specifications

• Filter type: circular polariser (CPL)
• Filter diameter: 77 mm
• Optical coating: Multi Resistant Coating (MRC) for reduced reflections and easier cleaning
• Mount material: brass for durability and precise threading
• Finish: grease-free rotating ring for smooth adjustment
• Included: single filter

How to use

Screw the filter onto the front thread of a lens with a 77 mm diameter until it is secure but not overtightened. Compose the image and rotate the filter ring while observing the viewfinder or live view until the desired reduction of reflections and increase in color saturation is achieved. For maximum sky darkening effect, aim to shoot roughly at a 90° angle to the sun and avoid extremely wide focal lengths below approximately 28 mm (in 35 mm equivalent) for consistent polarization across the frame. When finished, rotate the filter back to a neutral position if needed and unscrew it carefully.

Usage recommendations

Use the polariser when photographing skies, bodies of water, foliage and glass to control glare and improve color rendition. For best results, monitor changes in exposure after attaching the filter and adjust shutter speed or ISO as the CPL can reduce light transmission. Store the filter in a protective case when not in use to preserve the MRC finish and brass threading.
