Some impressive features for a "cheap" camera.
I usually use small cameras (Bmpcc, a7s, 5d...) with a "gunner" wich keeps the formfactor small and helps you to get the necessary stabilisation with your body. I put another battery (audioroots 49wh) with an dummy adaptator for the a7s and a G3 reciever to get the sound from the sound recorder.
