The B and W 37mm XS-Pro 810 ND Filter can be used for achieving the required depth of field in a bright environment. You can attach the filter to mirrorless cameras and DSLRs with its slim brass mount. The filter has a 3.0 density that lowers the exposure by 10 stops. A 3-layer MRC multi-coating is provided through a thin-film technology where the outer layer resists dust and moisture while the inner layer reduces reflections to boost image saturation. This filter has a 37mm accessory thread that can be used for attaching lens covers and hoods.
