B+W Master High Transmission Circular Polarising Filter 52mm

The B+W Master High Transmission Circular Polarising Filter is a precision optical accessory designed for photographers seeking to control reflections and enhance colour in their images. This 52mm filter screws directly onto the front thread of compatible camera lenses, from super wide-angle to telephoto. Its primary function is to selectively block polarised light, which allows photographers to reduce or eliminate unwanted glare from non-metallic surfaces like water, glass, and foliage, while simultaneously deepening blue skies and increasing overall colour saturation and contrast. Constructed with high-quality optical glass, the filter features B+W's MRC Nano (Multi-Resistant Coating Nano) technology. This multi-layer coating provides exceptional protection against water, grease, and dirt, making the filter easier to clean and maintain. A key practical feature is the specially treated, grease-free rotating ring, which allows for smooth adjustment of the polarising effect even in challenging conditions. The filter is mounted in a robust, precision-machined brass frame, ensuring durability and a perfect fit without risking damage to the lens thread. This filter is ideally suited for landscape, architectural, and travel photographers who frequently encounter reflective surfaces or wish to maximise colour vibrancy in outdoor scenes. Its colour-neutral transmission ensures that image colours remain true and natural. Being a circular polariser, it is fully compatible with all modern autofocus and metering systems. As a dedicated filter, it becomes a fundamental part of a photographer's toolkit for achieving professional results directly in-camera, reducing the need for extensive post-processing to remove glare or boost colours.
