Lens Filters – Which one do I need?

Choosing ND Filters

DJI has different official ND filters for their drones and cameras, like ND4, ND8, ND16, ND32, ND64, ND128, and more. 

The number associated with an ND filter indicates that how much light enters the lens in terms of a fraction.

  • ND4 reduces light by 1/4. An ND4 filter can reduce 2 stops of light, allowing you to slow the shutter speed from 1/100s to 1/25s.
  • ND8 reduces light by 1/8. An ND8 filter can reduce 3 stops of light, allowing you to slow the shutter speed from 1/200s to 1/25s. This one cuts 3 stops of light and is good for slight motion effects, like smoothing out rushing water.
  • ND16 reduces light by 1/16. An ND16 filter can reduce 6 stops of light, allowing you to slow the shutter speed from 1/400s to 1/25s.
  • ND64 reduces light by 1/64. An ND64 filter can reduce 4 stops of light. It’s often used to blurred motion effects in bright daylight.
