K&F Concept 100x100mm ND16 Square Filter 4 Stops Neutral Density Filter with 28 Multi-Layer Coatings

K&F Concept 100X100mm Square ND16 (4 Stop) Neutral Density Filter with 28 Multi-Layer Coatings

--The K&F Concept Filters 100 x 100mm Neutral Density ND16 Filter is a fixed neutral density filter providing a 4-stop reduction in exposure.
--This filter is constructed from a high quality import HD optical glass. It is compatible with the 100mm Filter holder system, which is designed for use with most lenses and camera types.
--28 Multi-Layer Nano Coatings，Our optical engineers developed new nano coating layer technology, called nanotec, from the ground up to repel dirt, water and other elements by beading rather than absorbing and smearing. Set in our workhorse and built to withstand extreme wind, salt water, dust and other abrasive conditions and elements.

Feature
1.K&F Concept ND16 will catch 4 f-stops of light, dedicating its use to long-exposure photography and/or depth of field reduction in extremely bright conditions for video shooting.
2.Allows the use of slow shutter speeds, with high-speed films or digital cameras, to record movement/image blur in subjects.
3.Decrease the depth of field by using wider apertures, which helps separate subjects from their background.
