B + W Filter Company 30.5mm Master 007M Clear MRC Nano Filter

SKU CH-1HS1-CNBA4

A 30.5 mm clear protective filter with hydrophobic MRC nano-coating that repels water, dirt and sand while reducing reflections for colour-neutral, exposure-free lens protection

  • Hydrophobic coating repels dirt, sand and moisture
  • Easy-clean surface cuts reflections for clearer images
  • Color-neutral glass preserves true colours without tint
  • Advanced MRC nano-coating minimises light reflection interference
  • No exposure compensation needed, maintaining image balance

Lens Protection

The B+W 30.5mm Master 007M Clear MRC Nano Filter safeguards valuable camera lenses from dirt, sand, moisture and fingerprints. Its hydrophobic coating repels water and particles so the front element stays clean in challenging conditions. The filter is colour-neutral and highly transparent, making it suitable for permanent attachment without affecting image balance. No exposure compensation is required when the filter is in place.

Ideal Users

Photographers who shoot outdoors, in dusty environments or near water will benefit from the easy-clean surface and reduced reflection. The 30.5mm thread size fits only lenses with that exact diameter, so owners of larger or smaller front threads cannot use this model. Buyers who need creative effects such as polarisation or neutral density should choose a different filter type. Anyone without a 30.5mm lens will find this filter incompatible.

Critical Spec

The filter thread measures 30.5mm and matches lenses marked with that size. Manufacturer part reference 66-1101513 confirms the exact model for ordering. Verify the lens barrel or cap for the 30.5mm marking before purchase.

Questions about this item

Does the 30.5mm Master 007M filter add any exposure shift during all-day shooting?

No exposure compensation is needed; the filter is colour-neutral and highly transparent so image brightness stays consistent.

What lens thread size must my lens already have for this filter to fit?

Your lens needs a 30.5mm front thread; the filter screws directly onto that thread.

Will the hydrophobic MRC nano coating on this 30.5mm filter work with older lenses that lack modern coatings?

Yes, the coating is independent of the lens; it repels dirt, sand and moisture and reduces reflections on any 30.5mm thread.
