The B and W 82mm XS-Pro 810 ND Filter is made from finely cut polished glass. This filter can be attached to mirrorless cameras or DSLRs with the slim brass mount. This neutral-density filter retains the original image coloration and allows you to work with a slow shutter speed and wide aperture in bright light. The filter features multi-layer MRC-nano coating applied using the thin-film technology to offer rich images. The inner anti-reflective part exhibits 7 layers on each side of the filter. This filter has an 82mm accessory thread that can be used to fit a lens cover or hood.
