Hi Forum, I was here a little while back about a D610 that I bought used with a non-functioning internal mic. In the end and after negotiating with the seller, I took it to get fixed. The mic now works but I find the sound quality really appalling. I sent a message to the technician who said that this is normal but that I could bring the camera back. Here is a link to the video test that I sent to the technician. Can the internal mic really sound this bad? Thanks!
