The B and W 46mm XS-Pro 810 ND Filter is made from finely cut, polished glass and serves as a one-stop solution for producing color-neutral images. It is specially made for mirrorless cameras and DSLRs. The filter enables you to use a low shutter speed and wide aperture without experiencing reflections. A filter density of 3 translates into reduction in exposure by 10 stops. Three different coatings are applied on this neutral-density filter using the thin film technology. The inner part minimizes reflections with 7 layers of anti-reflective coating on each side, and the outer layer resists dust and moisture. You can fix a lens cover or hood onto the front 46mm accessory thread.
