I'm in the market for a wireless lavalier mic, and was hoping I could get some advice. My knowledge of fine audio is fairly limited, and I haven't been able to find any good online resources which review such products... so any help would be much appreciated. I use a Panasonic GH2 DSLR for all of my video shoots. I primarily do interview style videos, but often the subjects are moving about. Top priority is that it's high quality stereo sound, also don't want to pay an arm and a leg. Right now I'm using a cheap wired lavalier mic... the sound is good, but it's only mono. Hopefully the main unit is fairly compact so its easy to manage around the GH2. Thank you for the advice!
