Overview

The B+W 1101574 49mm ND 1.8 MRC Nano Filter is part of B+W's Master series, engineered for photographers who need precise, neutral light reduction without compromising image quality. Its 6-stop (ND 1.8) density reduces the light reaching the sensor by a factor of 64, opening up creative possibilities that would otherwise be unavailable in bright shooting conditions. Landscape photographers can achieve silky smooth water and cloud movement with multi-second exposures in broad daylight, while portrait and video shooters can open up to wider apertures for shallow depth of field without overexposing the frame.

The MRC nano coating is a defining feature of the Master line, applying multiple layers of anti-reflection treatment along with a hydrophobic and oleophobic top layer that causes water to bead and roll off and makes fingerprints and dust easy to wipe away. This keeps the filter optically clean in rain, mist, or dusty environments where cheaper uncoated filters would quickly degrade image quality. The black knurled thin-profile brass mount provides a confident grip for threading the filter on and off while keeping the overall stack height low enough to avoid vignetting on lenses as wide as 17mm on full frame. A scannable QR code on the packaging lets buyers confirm they have a genuine B+W product, not a counterfeit — a useful assurance given the prevalence of imitation filters in the market.

Pros & Cons

👍 Pros

  • MRC nano coating effectively repels water, dust, and fingerprints, keeping the filter clean during outdoor shoots.
  • The 6-stop density is versatile enough for smooth water effects, motion blur in daylight, and shooting wide-open in bright light.
  • Thin profile mount minimizes vignetting risk on wide-angle lenses down to 17mm full-frame equivalent.
  • Black knurled mount edge provides a secure, non-slip grip when attaching or removing the filter.
  • Includes a QR code for verifying authenticity, giving confidence the filter meets B+W's optical standards.

👎 Cons

  • At 49mm, this filter size fits only smaller lenses — photographers with multiple lens diameters will need separate filters or step-up rings.
  • A single 6-stop density may not be enough for very bright midday conditions where 10-stop or stronger filters are preferred for extreme long exposures.
  • Premium B+W pricing is significantly higher than budget ND filters, which may be hard to justify for occasional use.
  • The filter does not include a dedicated hard case for protection, relying on the eco-friendly packaging for storage.

Frequently Asked Questions

It provides 6 stops (ND 1.8 / ND 64) of light reduction, allowing you to use shutter speeds 64 times longer or apertures 6 stops wider than you could without the filter.
B+W's Master series ND filters are designed for neutral color rendition. The MRC nano coating also minimizes reflections that can contribute to color shifts, though very long exposures may show a slight warm cast as with most glass ND filters.
MRC (Multi-Resistant Coating) nano is a multi-layer coating that repels water, dirt, and fingerprints from the filter surface, making it easier to clean in the field and reducing ghosting and flare from reflected light.
The thin profile mount is rated good for lenses down to 17mm equivalent on full frame, so it should not vignette at standard wide-angle focal lengths. Extremely wide or ultra-wide lenses below 17mm may show corner shading.
Each filter includes a QR code on the packaging that you can scan to verify authenticity directly through B+W.
