The NEEWER square ND1.8(6 Stops) 4" x 5.65" / 10.16 x 14.35cm filter enables more control over shutter speed and aperture, avoiding overexposure and helping to balance image exposure, perfect for shooting in bright sunlight, creating motion blur.

Not being directly screwed onto the lens, the square ND filter can be used for lenses of various focal lengths when mounted on a matte box

  • Double Sided Multi Layers of Nano Coatings- The multiple layers of Nano coatings on both sides make the filter scratch resistant, water repellent, oil proof and fingerprint resistant. Use the included cleaning cloth to clean the filter

  1. The square ND filter can’t directly screw onto your camera lens. It has to be mounted on a matte box or filter frame to be placed in front of your camera lens. Compatible with Tilta SmallRig Matte Box, Mini Matte Box, and Filter Frame.
  2. The number 1.8 in the ND1.8 filter stands for the optical density of the filter. The higher the value, the greater density the filter has and the less the light transmits.
