K&F Concept X-Pro Square ND Filter with Frame (100 x 100, 6-Stop)

This X-Pro Square ND64 Filter from K&F Concept is made for the X-Pro Square Filter Holder System. This 100 x 100mm filter reduces exposures by 6 stops, making it possible to increase shutter speed length or lens aperture. Increasing shutter speed helps to create increased image motion blur, like when smoothing rivers, waterfalls, and clouds when shooting landscapes. Increasing aperture allows wider apertures to be used for finer control over depth-of-field, to help isolate a subject form the background.
