The B and W 46mm XS-Pro 806 ND Filter makes it easy control the depth of field in bright lighting. This filter can be fitted to mirrorless cameras and DSLRs with its slim brass mount. The filter density of 1.8 offers a 6-stop exposure reduction, thus allowing you to decrease the shutter speed and widen the aperture without the fear of overexposure. A thin-film technology is employed for applying 3 different coatings to the filter, in which the inner layer reduces reflections to improve saturation, and the outer layer prevents dust and moisture from affecting the filter surface. You can attach a lens cover or hood to the front 46mm accessory thread.
