B+W 1101572 43mm Master ND 1.8 MRC Nano Filter

The B+W 43mm Master ND 1.8 MRC Nano Filter (1101572) is a professional-grade neutral density filter that reduces light transmission by six stops. This allows photographers to use wider apertures for shallow depth of field or slower shutter speeds for motion blur effects — even in bright conditions where those settings would otherwise result in overexposure. The filter is constructed from finely polished glass that maintains sharpness and delivers color-neutral results, ensuring that the only change to your image is the amount of light reaching the sensor.

The MRC Nano coating is a standout feature, applying a hydrophobic and oleophobic layer that causes water to bead and roll off the surface while resisting fingerprints and dust. This is particularly valuable during outdoor shoots where the filter is exposed to the elements. The black knurled thin profile mount provides a secure grip for easy installation and removal, and its slim design minimizes the risk of vignetting on wide-angle lenses down to 17mm on full-frame cameras. An included QR code allows buyers to verify the filter's authenticity, and the eco-friendly packaging reflects B+W's environmental commitment.
