I've only used a Sony A7rii and Deity D3 Pro for audio, but the preamps in Sony mirrorless cameras are notoriously bad. I had to crank the gain very high on d3 and ended up picking up a lot of room noise, which isn't very good. That being said, I can set the gain to 0 for the microphone and 1 for the camera. Now I get a very clear sound - no room noise or reverberation. There are sellers selling this for $91 which is a bargain and I recommend a refurbished model (I bought a refurbished one). A fantastic addition to any YouTuber setup.
