I have been shooting the Sony 760 and we recently picked up the NX30. I tested it out today here in Austin at a BMX contest. I really like this camera. I still have quite a bit to learn within the menu's to get the best picture but for documentary, BTS, and overall fantastic small camera to take anywhere,,,, I love it.
Its great to have a camera with great audio that I can cut in with other camera's we shoot with. Most of all the AUDIO.
DISCLAIMER: This is a hack cut and my first time using the camera. Cut in FCPX with limited color correction.
