Číry fotografický filter B+W 007 MASTER 3,9 cm Multi Resistant Coating

The B+W 007 MASTER Clear camera filter is a transparent protection filter with Multi Resistant Coating (MRC) designed to safeguard the front element of photographic lenses without altering image color or exposure. With a diameter of 3.9 cm, the filter reduces surface reflections and maintains high light transmission, making it suitable for continuous use on lenses exposed to dust, fingerprints, wind-driven sand and splashes.

Advantages

The filter provides permanent front-lens protection while remaining color-neutral and highly transparent. Its MRC coating minimizes reflections and glare so optical information reaches the sensor or film unchanged. Compared with replacing or repairing a lens, the filter is a cost-effective, easy-to-clean barrier that avoids frequent direct cleaning of the front element.

Suitable for

• Everyday outdoor photography where lenses are exposed to dust and moisture
• Active shooting in windy or sandy environments
• Situations requiring frequent lens handling to prevent fingerprints
• Use on zoom lenses or lenses with smaller apertures that are sensitive to front-element soiling

Key specifications

• Filter type: clear/protection filter
• Coating: Multi Resistant Coating (MRC)
• Optical behavior: color-neutral, high transparency, low reflection
• Diameter: 3.9 cm
• Intended use: permanent front-lens protection

How to use

Screw the filter onto the front thread of a compatible lens until secure, taking care not to cross-thread. The clear filter can remain mounted during shooting; it does not require exposure compensation. To clean, remove the filter and use a soft blower, lens brush or microfiber cloth with appropriate lens cleaning fluid if needed. Avoid abrasive materials and excessive pressure to prevent micro-scratches.

Recommendations

For digital photography, leave the B+W 007 MASTER filter on the lens to reduce the need for direct front-element cleaning. Regularly remove accumulated grit with a blower before wiping and store the lens with the filter attached or with a lens cap to maintain optimal optical performance.
