SKU CH-M18V-C8YF3

A 40.5mm circular polarizer with multi-resistant coating that reduces glare and reflections while boosting colour saturation and contrast

  • Enhances colour saturation and contrast for vibrant images
  • Multi-resistant coating cuts reflections, glare and flare while shielding against dust and moisture
  • Circular design minimises vignetting and delivers even light distribution
  • Rotating mount lets you adjust polarisation live through the viewfinder or screen
  • Reduces reflections from water, glass and glossy paint for clearer shots

Essential Polarising Filter

The B+W 40.5mm Basic Circular Polarizer MRC Filter fits lenses with a 40.5mm thread and is built for photographers who want richer colours and deeper contrast straight from the camera. Its circular design works with modern autofocus and metering systems on both digital and film bodies. The rotating mount lets you dial the effect while watching through the viewfinder or rear screen.

Multi-Resistant Coating Performance

A multi-resistant coating cuts reflections, glare and lens flare while repelling dust and moisture for easier cleaning. By suppressing stray light the coating helps maintain contrast in high-contrast scenes such as bright skies over water. The slim frame keeps vignetting to a minimum even at wider focal lengths.

Upgrade From Uncoated Or Basic Filters

Photographers moving up from uncoated or single-coated polarizers will see cleaner highlights and more neutral colour balance. The improvement is most noticeable when shooting reflective surfaces like glass, wet foliage or painted metal. Shooters who need a larger thread size or a nano-coated variant should look elsewhere.

Questions about this item

How do I install the 40.5mm Circular Polarizer MRC Filter and what step do people often get wrong?

Screw the filter onto the lens front thread until snug; the step many miss is rotating the front ring while viewing through the camera to dial in the polarisation effect.

What maintenance or replacement will the 40.5mm Circular Polarizer MRC Filter need later?

Clean the multi-resistant coating with a microfibre cloth and lens fluid when dust or smudges appear; replace the filter only if the glass is scratched or the coating degrades.

What limit shows up first when using the 40.5mm Circular Polarizer MRC Filter under sustained bright conditions?

The filter cuts about one to two stops of light, so exposure times lengthen and motion blur or camera shake becomes the practical limit in prolonged shooting.
