Normally I'm filming with the NEX-FS100, but last week I decided to take the NEX-5N with me and shoot some footage at the beach with the 18-200mm lens. I didn't alter the footage in any way and the sound you hear is from the internal microphone. It will sound better on a less windy day. :)

Overall, I'm very happy with the image quality.
Next time I will take a tripod with me, because this camera really deserves it.
