Sennheiser EW112-p G3 Camera Mount Wireless Microphone System with ME2 Lavalier Mic.
I have used these on many occasions for general vocal and instrumental recordings and the quality is outstanding. What makes this really convenient is that the receiver uses a 1/8" Stereo Mini jack to plug right into your 1/8" mini audio input on your camera. No adapters needed.
"But I need to record 2 people, how do I plug two of these into my camera"? you may be asking. In order to add a second mic to a camera that only has a Mini Plug in you need one of these bad boys. The
