The 3.5mm on the camera was the first thing I tried, and nothing happed…
But thanks for the advise, I’ll see how much they ask, and now that I know what I am looking for, I can check out if there is some ready-made solution.
I know that there are inexpensive XLR lav on Amazon, but I really like the sound quality of my Sony, and was hoping to be able to use it.
