B+W 52mm Master Clear MRC Nano 007M Filter - Clear Protection

In this review the B+W 52mm Master Clear MRC Nano 007M filter is evaluated as a straightforward protective accessory for photographers who want a permanently fitted, color-neutral barrier for their lens. The single biggest reason to buy is protection without image alteration: this filter is described as having no filter effect or light loss and stays color-neutral, so it can remain mounted as a lens protector. The inclusion of a knurled thin profile mount and the MRC Nano coating that repels water and dust are practical details that make it useful in everyday shooting and travel situations.

Key Features

• Black knurled thin profile mount: Provides a better grip for mounting and unmounting while minimizing vignetting on wide-angle setups.
• MRC Nano coating: Reduces reflections and improves transmission while shedding water and dust for easier field cleaning.
• No filter effect: Maintains neutral color and transparency so there is no measurable light loss or color shift in images.
• Good for 17mm full frame format: The thin mount is designed to work on lenses down to 17mm on full frame bodies without heavy corner shading.
• New QR code authenticity check: Allows buyers to verify the filter is genuine directly with the brand for confidence in purchase.
• ECO-friendly packaging: Reduces waste and is a small environmental plus for a routine accessory purchase.

Who It's For

The B+W 52mm clear filter is best for photographers who want simple, reliable protection for a 52mm front thread lens and do not want any color or exposure compromise. Landscape shooters, travel photographers, and anyone who leaves a protective element on the lens will appreciate the high transparency and low reflection.

It is less relevant for photographers who need specialized optical effects, such as polarizing or neutral density control, or for lenses that require larger or specialty filter shapes. If you need dramatic light control or creative color correction, look to dedicated effect filters instead.

Pros & Cons

Pros

• Neutral, high-transmission glass that can remain mounted without altering color or exposure.
• Durable MRC Nano coating that repels water and dust and reduces surface reflections.
• Thin, knurled mount for secure handling and reduced risk of vignetting on wide lenses.
• Includes a QR code for authenticity verification and comes in eco-friendly packaging.

Cons

• Not a substitute for polarizers or ND filters when you need creative exposure or polarization control.
• Protection is limited to the front element; it does not guard against mechanical impact beyond standard glass strength.
