Here is a video handle with an integrated stereo microphone that lets you capture quality audio to go along with video captured with your smartphone, GoPro, or DSLR camera. The MicRig has a rugged design and works with a wide variety of cameras. You can mount it to a tripod via 1/4-20 mounting thread.
The kit ships with smartphone and GoPro adapters and cables. The shoe-mount lets you add lights and other gear. Expected to ship in May.
