The DJI Mavic 4 Pro Filters set includes ND8, ND16, ND32 and 64 filters. With the ND filters, you can get the shutter speed required for video shooting in different lighting conditions.

DJI's original set of three ND filters for the DJI Mavic 4 Pro drone.
To ensure that the video image is smooth to the eye, the shutter speed should be 2x the framerate used in the video recording. In other words, if you are shooting at 25fps, the shutter speed should be 1/50, and if you are shooting at 50fps, the shutter speed should be 1/100, and for 120fps, 1/240.
ND filters help you achieve the shutter speed required for video shooting in different lighting conditions and avoid jerky or horizontal noise in the image caused by high shutter speeds.
ND8 lets 1/8 of the incoming light through and is suitable for sunny weather.
ND16 lets 1/16 of the incoming light through and is suitable for bright weather.
ND32 lets 1/32 of the incoming light through and is suitable for bright weather, for example snowy Lapland on a sunny day.
ND64 lets 1/64 of the incoming light through and is suitable for really bright weather, for example snowy Lapland on a sunny day.
Compatible with DJI Mavic 4 Pro
