A:Answer ND filters can matter on almost any camera drone, especially for video capture. The Air 2 has a fixed aperture, meaning you can only adjust shutter speed to limit how much light hits the sensor. Rule of thumb is to set your shutter speed to twice your frame rate ( 30 fps -> 1/60 shutter, 60 fps -> 1/120 shutter, etc ). On sunny days a 1/60 or 1/120 shutter is often too slow and will overexpose the capture, even if using ISO 100. Shooting video with a very fast shutter makes it look choppy and artificial. The ND filters cut down the light entering the lens, giving you more flexibility in setting your capture parameters.
The filters are helpful for still photography when you are shooting REALLY bright scenes ( sunrises/sunsets ) or if you need a long exposure for a particular effect.
