Now that I am using the Sony a7 series, the built in pre amps seem to be "good enough" so I can plug a wireless unit directly into the camera and get audio "good enough" for...
Sorry for my ignorance but I see these stereo mics and wonder if they would serve any purpose inputting into something like the Sony a7 camera series or the Sony PCM 10 recorder:
I am especially interested in what use I might be able to make of those hand held mics with the x-y (?)...
