Circular Polarizer Filter B+W T-Pro HTC MRC Nano 77mm — 77 mm circular polarizing camera filter

The Circular Polarizer Filter B+W T-Pro HTC MRC Nano 77mm is a 77 mm circular polarizing camera filter designed to reduce surface reflections and enhance color saturation in photography. It fits lenses with a 77 mm front thread and combines multi-resistant coating (MRC) with a Nano top coat to improve water and dirt repellence and simplify cleaning. The filter is intended for photographers seeking better contrast, deeper skies and reduced glare in outdoor, landscape and architectural shots.

Advantages

The filter reduces unwanted reflections from non-metallic surfaces such as water, glass and foliage, yielding richer color rendition and stronger contrast without digital post-processing. The multi-resistant coating lowers flare and ghosting while the Nano surface treatment makes smudges and moisture easier to remove. The circular polarizer design preserves autofocus and exposure metering performance on modern cameras.

Suitable for

• Landscape photography to deepen skies and increase color saturation
• Architectural photography to reduce window and facade reflections
• Outdoor and travel photography where glare from water or foliage is present
• General-purpose use when improved contrast and color clarity are desired

Key specifications

• Filter type: Circular polarizer (CPL)
• Mount diameter: 77 mm thread
• Optical glass quality with multi-resistant coating
• Nano surface treatment for improved water and dirt repellence
• Low-profile metal frame to reduce vignetting on wide-angle lenses

How to use

Attach the filter to the lens by screwing it into the 77 mm front thread until secure, taking care not to overtighten. Compose and focus as usual, then rotate the outer ring of the polarizer while observing the viewfinder or live view to adjust the degree of polarization. Stop rotating when reflections are minimized and the desired color saturation and contrast are achieved. If using wide-angle lenses, check for uneven polarization across the sky and adjust composition if necessary.

Usage recommendations

For best results, use the circular polarizer at mid-range focal lengths and when the sun is at an angle to the subject rather than directly behind the camera. Clean the Nano-coated surface with a soft microfiber cloth and, if needed, a mild lens cleaner to preserve the coating. Store the filter in a protective case when not in use to avoid scratches and contamination.
