B+W ND 0.9 MRC Nano Master 40.5
B+W ND 0.9 MRC Nano Master 40.5 | Gain three stops for longer exposures
For a softer sense of movement in bright conditions, or a wider aperture in strong light, an ND filter lets you reduce the light reaching the camera. The B+W ND 0.9 MRC Nano Master 40.5 is a neutral-density filter with a 0.9 density, giving you approximately three stops of light reduction. That makes it useful for slowing a shutter speed without changing the scene’s lighting, or for opening the aperture while keeping exposure under control. It suits photographers who want to shape motion in water or clouds, and those making portraits outdoors who need more room to choose an aperture. The 40.5 size is intended for a lens with a matching filter thread. Its name also identifies the MRC Nano coating and Master series, so you can distinguish it from other B+W filter versions when choosing or organising your kit.
Specialist Note
Harsh daylight can leave you with no room to slow the shutter or open the aperture; this filter gives you three stops of breathing space. I’d consider it for a small 40.5 mm-thread lens when you want moving water to blur gently: if your starting exposure is 1/125 sec, the same exposure with the filter is about 1/15 sec. For an outdoor portrait, those three stops can also help you use a wider aperture in bright light. The ND 0.9 strength is fixed, so it’s a straightforward, predictable reduction rather than an adjustable range. The MRC Nano Master name is useful when you want to identify this specific B+W version.
