RF70 Lens Set includes ND2, ND4 and ND8. These neutral density filters allow you to get more accurately exposed shots in different lighting scenarios. By reducing extra light entering the camera, these ND filters help avoid over-exposing film in bright sunlight.

Using a larger aperture of f/5.6, you can achieve shallow depth-of-field in brightly lit conditions. This is perfect for outdoor shooting and long shutter exposures.
