I just got my nex5n today and it is awesome! I have not flown it yet and probably wont for a hwile until i gain more confidence in my new craft. At first i thought the rattling was in the lens and therefore probably part of the stabilization system, but it is definitely in the body. You have to shake the camera though to get the sound and it really doesnt affect the performance, just kinda cheap on Sony's part to release it this way. BUT, the quality is amazing, super fast focusing, nice crisp display, amazing image stabilization! and 1080 60p. I'm happy. I wish all cameras would just integrate a damn intervalometer though! now to test the hdmi live output for myself.
