B+W 72mm Basic Circular Polarizer MRC Knurled video accessory

Polarising filter for 72 mm threads

The B+W 72 mm Basic Circular Polarizer MRC is a rotating screw-in filter designed for photographers and videographers who need to cut glare from non-metallic surfaces such as water, glass or glossy paint. Its circular construction preserves autofocus operation on modern lenses while deepening colour saturation and contrast. The black knurled mount provides a secure grip for quick adjustments in the field.

Check thread size and vignetting risk

Before ordering, confirm that the lens you intend to use carries a 72 mm filter thread; the size is usually marked on the barrel or front cap. On wide-angle zooms, test at the shortest focal length to ensure the filter frame does not intrude into the corners — the manufacturer notes compatibility down to 24 mm on full-frame formats, but individual lens hoods or protruding front elements can still cause shading.

MRC coating and authenticity code

The Multi-Resistant Coating suppresses flare and ghosting when shooting toward bright light sources, helping maintain image clarity in high-contrast scenes. A QR code printed on the packaging links to a verification page so you can confirm the filter is a genuine B+W product. The filter ships in eco-friendly packaging that reduces plastic waste without affecting optical performance.
