Clear camera filter B+W 007 MASTER 9.5 cm Multi Resistant Coating

The B+W 007 MASTER Clear camera filter is a transparent protection filter for the front element of photographic lenses. With a diameter of 9.5 cm and a Multi Resistant Coating (MRC), the filter is color-neutral and highly transparent, minimising reflections and preserving the optical information that reaches the image sensor. It is intended to stay mounted permanently to protect the lens from dust, sand, fingerprints and splashing water without affecting exposure settings.

Advantages

The filter provides durable protection for the front lens element at a fraction of the cost of lens repair or replacement. Its MRC treatment reduces surface reflections and eases cleaning, while maintaining colour neutrality and high light transmission so that image quality and exposure remain unchanged. The design allows continuous use on the lens, helping to avoid frequent front-element cleaning that can introduce scratches or carry contaminants into the lens.

Suitable for

• Outdoor and travel photography where lenses are exposed to dust, sand or spray
• Everyday use to protect expensive front elements from fingerprints and accidental contact
• Digital photography with smaller sensors where front-element contamination more readily affects image quality
• Photographers who prefer leaving a protection filter mounted permanently

Key specifications

• Filter type: clear (protection) filter
• Diameter: 9.5 cm
• Coating: Multi Resistant Coating (MRC)
• Optical properties: colour-neutral, high transparency, low reflection

How to use

Screw the filter onto the front thread of a compatible lens until it is secure; ensure the thread and filter are clean and free of grit before mounting. The filter can remain mounted permanently during shooting; normal exposure settings are retained because the clear filter does not change light transmission in practice. Clean the coated surface gently with a suitable lens cloth or blower to remove loose particles, and use lens cleaning fluid sparingly on stubborn marks.

Usage recommendations

To reduce the need for frequent deep cleaning of the front element, keep the B+W 007 MASTER filter mounted during active outdoor use. When removing and storing the filter, keep it in a protective case to avoid scratches and contamination.
