The K&F ND filter is a versatile neutral density filter with a diameter of 67 millimetres, making it ideal for photographers and videographers who desire precise control over the exposure of their shots. This adjustable variable ND filter allows for the adjustment of the amount of light hitting the sensor, ranging from ND8 to ND2000. This provides the flexibility to achieve optimal results in both bright lighting conditions and shaded environments. The filter easily screws onto the lens and is equipped with a robust housing that ensures ease of use. The grey colour group ensures that the colour reproduction of images is not compromised, while the ability to adjust the filter's density allows for creative effects such as motion blur or reduced depth of field.
