The Benro 100 x 100mm Universal Series ND 0.9 Filter is a neutral density filter with an 8x filter factor that provides a 3-stop exposure reduction. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
Each surface is coated to offer greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The coatings associated with Benro Universal Series neutral density filters also result in an improved beading effect when in contact with water for greater cleaning efficiency.
This filter is constructed from durable, optical resin and measures 2mm thick.
