Mavic 4 PRO - how are the ND filters by DJI / Freewell and Startrc

[maurotandoi]

For those who are interested I show how the filters are on the side of the attack.

As you can see, there are screws on the drone.

The original DJI filters have metal plates, these would seem to be placed so as not to scratch the small screws placed under the filter (..Maybe also to discharge the electrostatic charges because of the energised eND PINs?)
