Dolica CF-NDK52 52mm Neutral Density 0.3, 0.6, 0.9 Glass Filter Kit

The CF-NDK52 Neutral Density Filter Kit designed and used to reduce the amount of light passing through the lens so that a longer exposure is required to record an image. The ND filter is commonly used for longer exposure to emphasize movement, such as photographing waterfalls to enhance the blurred effect of the moving water. Another common use of ND filters to allow use of wider apertures to reduce depth of field.
