B+W 39mm Master UV Haze MRC Nano 010M Filter - Clear Protection

In this review the B+W 39mm Master UV Haze MRC Nano 010M is evaluated as a simple, reliable lens protector and color-neutral UV filter. It is best for photographers who want unobtrusive protection and improved clarity in bright outdoor conditions, because the 010M blocks invisible UV components that can cause haze or a blue cast in mountain and ocean scenes. The review finds the thin-profile, knurled mount and modern MRC Nano coating particularly useful for frequent outdoor use and quick cleaning, while the included QR code helps confirm authenticity.

Key Features

• Black Knurled Thin Profile Mount: The knurled edge gives a firmer grip when attaching or removing the filter, while the thin profile reduces vignetting on wide-angle lenses down to 17mm full frame.
• MRC Nano Coating: The multi-resistant coating repels water and dust, making it easier to wipe the filter clean after shooting in damp or dusty environments.
• Color-neutral UV Cut: The 010M element blocks UV components without shifting color, helping avoid bluish casts in high mountain and ocean photography.
• Lens Protection: Acts as a sacrificial front element to protect expensive lens glass from scratches, fingerprints, and light impacts during field use.
• Authenticity QR Code: A new QR code on the package lets buyers verify the filter is genuine before use, which matters for long-term quality and coating performance.
• ECO-Friendly Packaging: The filter ships in reduced-impact packaging that lowers waste without adding bulk to the product.

Who It's For

The B+W 39mm Master UV Haze MRC Nano 010M is aimed at landscape and travel photographers using compact lenses that accept 39mm filters, especially those who shoot near the ocean or at high elevations where UV haze is common. Its thin profile makes it suitable for wide-angle full frame lenses down to 17mm where vignetting becomes a concern.

Photographers who need variable neutral density, polarizing effects, or larger professional filters should look elsewhere, since this is strictly a UV-cut protector. It also assumes you have a lens with a 39mm thread; those with other sizes will need an appropriate filter or step-up ring solution.

Pros & Cons

Pros

• Effective color-neutral reduction of UV-induced haze in bright outdoor scenes.
• Thin, knurled mount provides better grip and minimizes vignetting on wide lenses.
• MRC Nano coating sheds water and dust, simplifying field cleaning and maintenance.
• Package QR code helps verify authenticity and avoid counterfeit purchases.

Cons

• Limited to UV-cut and lens protection only; no polarizing or neutral density functions.
• Only available in 39mm thread size, so many users will need adapters for other lenses.

Yes, the MRC Nano coating repels water and dust and makes wiping off smudges simpler than on uncoated glass.
