B+W 55mm Master Clear MRC Nano 007M Filter - Low Reflection Protection

Our review of the B+W 55mm Master Clear MRC Nano 007M finds it best suited to photographers who want unobtrusive, long-term lens protection without changing image color or exposure. The bottom line: this filter is essentially invisible in normal shooting and resists water and dirt thanks to the MRC Nano coating, so users who keep a filter on permanently will appreciate the durability and near-zero impact on image quality. It is a practical choice for landscape, street, and travel shooters using lenses down to 17mm on full frame.

Key Features

• Black knurled thin mount: The thin-profile, knurled edge improves grip for quicker threading and reduces vignetting on wide lenses down to 17mm full frame.
• MRC Nano coating: The multi-resistant coating repels water and dust, keeping the optical surface clearer in wet or dusty conditions for less cleaning.
• No filter effect: The clear glass is color-neutral and highly transparent so it does not alter exposure or color balance when left on the lens.
• Low reflection: Extremely low reflection performance helps maintain contrast and minimizes flare compared with uncoated protection filters.
• Authenticity QR code: The included QR code lets buyers verify the filter is genuine, reducing the risk of counterfeit glass.
• ECO-friendly packaging: The filter ships in reduced-impact packaging, which is a small sustainability benefit for buyers.

Who It's For

The B+W 55mm Master Clear suits photographers who want continuous lens protection without compromising image quality: landscape, travel, and street photographers will value the color-neutral glass and reduced reflections. Photographers who frequently encounter rain or dust will benefit from the MRC Nano coating that sheds contaminants and simplifies cleaning.

Those looking for specialty optical changes, such as UV cut, polarization, or color correction, should look elsewhere because this is a neutral protection filter with no creative filtering effect. Users with very large or specialty front elements should verify compatibility, though it is specified for lenses reaching 17mm on full frame.
