B+W 67mm Master Clear MRC Nano 007M Filter - Low Reflection Protection

In this review the B+W 67mm MASTER 007M Clear Knurled Filter is assessed as a no-nonsense lens protector for photographers who want permanent front-element coverage without color cast or light loss. It is best suited to landscape, street, and travel shooters who prefer leaving a clear filter on their lens; the single biggest reason to buy is the combination of high transparency and the MRC Nano coating that repels water and dust while keeping reflections extremely low. The review focuses on handling, optical neutrality, and everyday durability rather than dramatic creative effects.

Key Features

• Black knurled thin mount: the thin profile reduces vignetting on wide lenses and the knurling gives a better grip when mounting and removing the filter.
• MRC Nano coating: repels water and dust so droplets bead up and contaminants wipe away with less effort, helpful in wet or dusty conditions.
• Color-neutral clarity: the glass is highly transparent and designed to have no filter effect, so images retain original color balance and exposure.
• Low reflection: multiple coating layers produce extremely low surface reflections, maintaining contrast and reducing ghosting on digital sensors.
• QR code authenticity check: the included QR code lets buyers verify the filter is genuine for peace of mind when investing in protective glass.
• ECO-friendly packaging: packaging is designed to be low impact, useful for photographers mindful of material waste.

Who It's For

The B+W 67mm MASTER 007M is ideal for photographers who want a permanent protective element on a 67mm lens and need reliable optical neutrality; landscape and travel shooters who work in mixed weather will benefit most from the water-repellent MRC Nano coating. Its thin profile makes it a good match for wide-angle or full-frame setups down to around 17mm where vignetting and light falloff are a concern.

Photographers seeking creative filtration (neutral density, polarizing, or color correction) should look elsewhere, since this product is a clear protective filter with no effect on exposure or color. Those using lenses with non-67mm threads or preferring drop-in solutions for filters will need a different accessory.

Pros & Cons

Pros

• Excellent optical neutrality with no perceived color cast, so images remain true to the lens native output.
• MRC Nano coating makes cleaning quicker and reduces water spotting in damp conditions.
• Thin knurled mount minimizes vignetting on wide lenses and improves handling when changing filters.
• QR code for authenticity adds reassurance when purchasing genuine B+W glass.

Cons

• Offers no creative effect or exposure control since it is a clear filter, so additional filters are still required for specific photographic needs.
• Only fits lenses with 67mm front threads, so step-up or step-down rings may be needed for other sizes.
