I've heard different things about this. Some youtube videos say its okay to use your cameras mic as long as the subject isnt more than a few feet away. Others have told me, though that I need to use a sound guy. Since this is documentary/Blair With style, a sound guy isn't practical. If I buy an external mic that attaches to the camera (Sony FDR-AX53), do you all think that will be good enough for most scenes, as long as the characters are within a few feet of the camera? Thank you for any feedback.
