B+W 39mm Basic Clear MRC 007M Glass Filter - Neutral Protection

In this review the B+W 39mm Basic Clear MRC 007M is evaluated as a simple, durable lens protector for photographers who want zero color cast and reliable flare control. The bottom line: it is for shooters who prefer to leave a clear filter on their lens permanently to safeguard front elements without altering exposure or color. The reviewer found the filter to be highly transparent, effectively protected by the MRC coating, and convenient to grip thanks to the black knurled mount, making it a practical everyday accessory for glass that costs more to replace than the filter itself.

Key Features

• Black Knurled Filter Mount: Improved grip makes mounting and removal much easier, especially in the field or with cold hands.
• MRC Coating: Multi-resistant coating reduces flare and ghosting so images remain clear even with bright light sources in frame.
• No Filter Effect: The clear glass introduces no color shift or light loss, so exposure and white balance remain unchanged when left on the lens.
• Coverage to 24mm Full Frame: Suitable for use on lenses down to 24mm on full frame, avoiding vignetting on many wide lenses in that range.
• QR Code Authenticity: New QR code included to verify the filter is genuine and not a counterfeit product.
• ECO-Friendly Packaging: Reduced packaging waste makes this an environmentally considerate choice for routine protection.

Who It's For

The B+W 39mm Basic Clear is best for photographers who own lenses with a 39mm front thread and want a transparent permanent protector that will not alter image color or exposure. Street, travel, and outdoor photographers who often keep a filter on a lens for physical protection will appreciate the low-reflection MRC coating and the knurled mount for quick handling.

It is less suitable for users who need optical correction, UV-specific filtration, or polarizing and variable neutral density functions; photographers seeking specialized image effects or filtration should look at dedicated UV, polarizer, or ND filters instead of a basic clear glass protector.

Pros & Cons

Pros

• Very neutral optics preserve color and exposure so images remain true to the lens' character.
• MRC coating meaningfully reduces flare and ghosting in backlit or high contrast scenes.
• Knurled mount makes the filter easy to tighten and remove without extra tools.
• Includes a QR code for authenticity, helping buyers confirm they have a genuine component.

Cons

• As a clear protector it offers no UV reduction or polarizing benefit, so it does not replace functional filters.
• Limited to lenses with a 39mm thread, requiring step rings for other sizes.
