Designed to be used for specific types of photography, the B+W 82mm XS-Pro MRC-Nano 806 Solid Neutral Density 1.8 Filter (6-Stop) is a must-have for your camera lens. With a 1.8 density, this filter darkens your scene, thereby letting you take photos with a wider aperture or longer shutter speed. It offers an exposure reduction of up to six stops, which means that you can control the field depth and convey movement conveniently. Being a neutral-density filter, it does not affect your image’s coloration and can be used with other filters. This B+W filter’s surface is multicoated for preventing internal ghosting and reflections. The thin, brass ring on this filter provides it with added strength, as well as prevents jamming and vignetting. This B+W 82mm Neutral Density Filter is made from Schott glass to ensure optical clarity. This filter can be placed in the included plastic case for convenient portability and storage.
