If you own the DJI Mic 2 you have to buy the adapter

The new DJI Mic 2 Camera Adapter for Sony cameras is now in Stock at Amazon US&EU and at DJI store. This is a MUST buy accessory if you own the new DJI Mic 2 (Amazon US&EU, DJI store, BHphoto, Adorama.)

Philip Bloom tested it and wrote:

If you own a Sony cameras and these then it’s a no-brainer as it only cost me about £30 from the DJI store.
You need to update the firmware of the Mic 2 for this work. I’ve put the compatibility list in the comments. It worked on the FX6, FX3, a7siii, a1 and a7iv.
Whilst the RØDE Wireless Pro are a better set as they come with lav mics and have timecode, these are still great and are now the best budget dual wireless microphone system for for the Sony miShoe now. I’ve only come across one other that isn’t by Sony which is from Godox, but they aren’t in the same league. Don’t forget the DJI Mic 2 transmitters also record internally in 32 bit float.
