I realise that this is not a DJI product but I've posted this unboxing of the RODE VideoMic NTG as it may be of use for certain DJI cameras. In the video I also explain a certain amount of functionality about the microphone which may also be of use to certain DJI camera users.
I will also be doing some testing of this mic with the Action and Pocket, I'll post these as soon as they are done.
