B and W 39mm XS-Pro MRC-Nano 806 Neutral Density 1.8 Filter (6-Stop)

The B and W 39mm XS-Pro 806 ND Filter has a 64x filter factor that brings down the exposure by 6 stops. This ND filter sports a slim brass mount that makes it fit onto mirrorless cameras and DSLRs. Three different coatings are applied to the filter via a thin-film technology, in which the inner coating improves image saturation by reducing reflections while the outer layer protects the filter from dust and moisture. You can use a lens cover or hood on the 39mm accessory thread.
