The iFlight DJI O3 Air Unit ND filters set is a premium optical kit made for the DJI O3 digital transmission camera module. The listing says it controls light transmission without shifting colour accuracy and is optimised for freestyle pilots and commercial FPV cinematographers.
The glass is treated with double-sided, multi-layer nano-coatings that repel water droplets, finger grease and minor scratches, and each filter sits in a featherweight CNC-machined aluminium frame that clicks onto the O3 lens housing without upsetting the balance.
The set contains three density steps: ND8 (3-stop), ND16 (4-stop) and ND32 (5-stop). A rugged polypropylene case protects the filters.
High-definition multi-coating: double-sided nano-coatings repel water, grease and scratches.
Precision CNC aluminium rim: featherweight frame that clicks onto the O3 lens housing.
Three density steps: ND8, ND16 and ND32.
Ultra-light optical glass: tempered glass cores, under 1g per filter.
Press-fit clip installation: direct, secure attachment.
Protective case: rugged polypropylene storage shell.
A neutral density (ND) filter reduces the amount of light reaching the camera sensor without changing colour. In bright sun, a camera will use a very fast shutter speed, which freezes motion and makes video look choppy. An ND filter lets you use a slower shutter speed, which adds natural motion blur and gives smoother, more cinematic footage.
A common rule for video is to set the shutter speed to about double the frame rate. To reach that in bright light you need a filter: a lower number such as ND8 (3 stops) suits moderately bright conditions, while ND16 (4 stops) and ND32 (5 stops) suit very bright sun. Using the right filter means you can keep the aperture and shutter where you want them.
Keep the filter clean and handle it by the edges. Remove it in dim light, since it would darken the picture and raise the noise. Check that it is seated firmly before every flight, because a loose filter can fall off or vibrate against the lens.
