The 46mm Nano-D Lens Filter Kit from K&F Concept is an ND filter that reduces the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion. This ND64 neutral density filter reduces the exposure in the entire image area for finer image control. The added density makes it possible to slow down shutter speeds for added image blur to enhance the set of movement, useful when shooting sports or moving water. It can also be used to shoot with a wider aperture to reduce depth-of-field to help isolate the subject of an image. This filter combines the reflection- and glare-reducing function of a circular polarizing (CPL) filter with the exposure-reducing function of an ND8 neutral density filter to reduce the overall exposure. A circular polarizing filter reduces reflections and glare on surfaces like glass and water to help reveal subject details. It can also reduce atmospheric haze when shooting landscapes and in other outdoor conditions. Its multilayer coating prevents oil, fingerprints, and scratches from attracting to the lens. The slim design is lightweight and reduces the impact on light, which avoids dark corners for wide-angle shooting. It comes with a case, making it convenient to carry and store.
