This 82mm Nano MC ND Filter is an ND filter with a 1000x filter factor that provides a 10-stop exposure reduction. Its 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to 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.
Sirui Nano MC ND Filters are constructed from Schott optical glass for increased optical clarity as well as color fidelity. This 82mm Nano MC ND Filter also features a front mount with 95mm front filter threads, which helps to reduce the likelihood of vignetting with wide-angle lenses.
To help eliminate internal ghosting and reflections, each glass surface of this 82mm Nano MC ND Filter includes multiple layers of anti-reflection coatings. The filter is also coated for resistance to oil, static, dirt, and scratches, offering greater protection to the filter and helping it to stay clean for longer than with uncoated filters. The coatings are also hydrophobic, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
