Overview

The B+W 43mm Master Clear MRC Nano 007M filter is built for photographers who want top-tier lens protection without any compromise in image quality. Manufactured in Germany using high-quality optical glass and a precision brass mount, this filter maintains complete color fidelity and introduces no light loss. The black knurled thin-profile design provides a secure grip for easy installation and removal while minimizing the risk of vignetting, even on wide-angle lenses with focal lengths down to 17mm on full-frame sensors.

What sets the Master series apart is the MRC Nano coating, which creates a hydrophobic and oleophobic surface that actively repels water droplets, dust, and oily fingerprints. This means less time cleaning and more time shooting, especially in challenging outdoor conditions. The included QR code for authenticity verification adds peace of mind that you're getting a genuine B+W product, and the eco-friendly packaging reflects a modern commitment to sustainability. At just 0.88 ounces, this filter adds virtually no weight to your setup while providing a durable first line of defense for your lens.
