Marumi Grey Filter ND4X 49 mm

Marumi Grey Filter ND4X 49 mm | Create motion blur in bright light

The defining choice is the ND4X light reduction: it lets you use a slower shutter speed or a wider aperture when the scene is bright. As a grey neutral-density filter, it cuts the light reaching the camera to one quarter, giving you a two-stop adjustment without changing the scene’s lighting. That makes it useful for photographers who want more control over exposure in daylight, particularly when a faster shutter would freeze movement they’d rather show as a blur. It can also help you open the aperture while keeping your chosen shutter speed. This 49 mm filter is for a lens with a matching filter thread, so it’s a straightforward way to add light reduction to that lens. Its strength is a measured adjustment, rather than a dramatic cut in light.

Putting the light reduction to work

For flowing water or moving clouds, the slower shutter speed can turn movement into a visible trail. The same reduction can be useful for portraits outdoors when you want a wider aperture in bright conditions. Set your exposure with the filter in place, then adjust shutter speed or aperture to suit the effect you want. An ND4X is a moderate reduction, so it won’t replace stronger filtration when you need a much longer exposure in very bright light.
