  • Blocks UV haze for clearer outdoor shots

  • Colour-neutral glass preserves natural tones on film and digital
  • Standard 40.5mm mount fits a wide range of lenses
  • Permanent barrier shields front element from sand, dust and water splashes

What this filter is and who it's for

The B+W Master 010M UV Haze filter blocks ultraviolet light that can cause a blueish cast and reduced contrast in outdoor photographs. Its multi-coated MRC nano-coating cuts reflections and glare while maintaining colour neutrality for both analog and digital cameras. The 40.5mm thread mounts directly on compatible lenses to provide permanent protection against sand, dust, fingerprints and water splashes without requiring exposure compensation.

What to check before ordering

Verify that your lens has a 40.5mm filter thread; the size is usually marked on the front barrel or in the lens specifications. Ensure the front element rotates or extends during focusing, as a rotating front element may require re-adjusting the filter orientation after focusing. Confirm there is enough clearance for the filter frame if you plan to use a lens hood or cap simultaneously.

Who this suits and who should look elsewhere

Photographers who shoot outdoors and want a single filter that protects the front element while reducing UV haze will benefit from the durable coating and neutral colour balance. Buyers who need creative effects such as polarisation, neutral density or graduated density should look at dedicated filters for those purposes. Lenses with a different thread diameter require a matching size or a step-up ring, which is not included.
