The 77mm Benro Master Series 77mm 7-Stop Filterhas a 128x filter factor that provides a 7-stop exposure reduction. Its 2.1 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.

To prevent internal ghosting and reflections, each glass surface includes multiple layers of antireflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. The nano coating associated with Benro Master Series neutral density filters provides an additional 13th layer over each side of this filter, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

This filter is constructed from SCHOTT B270 glass for increased optical clarity as well as color fidelity and features a brass filter ring for enhanced durability and to prevent jamming .
