B and W 40.5mm XS-Pro MRC-Nano 810 Neutral Density 3.0 Filter (10-Stop)

The B and W 40.5mm XS-Pro 810 ND Filter reduces exposure by 10 stops and produces color-neutral images. This filter has a slim brass mount that facilitates attachment to mirrorless cameras and DSLRs. Equipped with the thin-film technology, this filter features MRC-nano multi-layer coating. The anti-reflective part with 7 layers on each side improves light transmission, and the outer layer prevents dust and water from affecting the lens surface. A 40.5mm accessory thread located at the front allows you to use a lens cover or hood with this filter.
