B+W 43mm Master UV Haze MRC Nano 010M Filter - Clear, Durable

In this review the B+W 43mm MASTER UV-Cut 010M filter is judged as a practical, color-neutral protector for small-diameter lenses and photographers who shoot in bright outdoor conditions. The bottom line: it is chiefly valuable as a lens protection and UV reduction accessory that keeps images free of blueish casts in high mountains and ocean scenes while offering easy handling thanks to a black knurled thin-profile mount. The review focuses on build, optical neutrality, and the MRC Nano surface treatment as the single biggest reason to buy for landscape and travel shooters.

Key Features

• Thin knurled mount: The black knurled thin profile gives a better grip for mounting and unmounting without adding significant vignetting on wide-angle lenses down to 17mm full frame.
• MRC Nano coating: The multi-resistant coating with a nano layer repels water and dust so the front element is easier to clean in wet or dusty conditions.
• Color-neutral UV cut: The 010M element blocks UV components of daylight while remaining color-neutral, preventing blueish casts in alpine and seaside photography.
• Authenticity verification: A new QR code is included with the filter to verify the product is genuine and to guard against counterfeit copies.
• ECO-friendly packaging: The filter ships in reduced-impact packaging, which keeps waste down and storage simple.

Who It's For

The B+W 43mm MASTER UV-Cut is ideal for photographers using compact prime or zoom lenses with a 43mm thread or step-up rings who want unobtrusive protection and cleaner images in UV-prone conditions. Landscape, travel, and outdoor shooters who frequently photograph at high altitude or near the ocean will appreciate the color neutrality and the water-repellent surface.

It is less relevant for photographers who need specialized filters (polarizers, ND, or high-precision optical glass beyond UV protection) or for users with larger filter threads. Studio photographers who never expose lenses to weather may find it unnecessary.

Pros & Cons

Pros

• Excellent mechanical grip from the black knurled thin profile makes frequent use easier.
• Reliable MRC Nano coating reduces smudges and speeds cleaning after exposure to spray or dust.
• Color-neutral UV cut preserves accurate tones in mountain and seaside scenes.

Cons

• Provides basic UV protection only and does not replace specialized filters like polarizers or neutral density options.
