An other comment, is even the

Another comment; even the great quality of the sony NEX on camera mic only works well if you are close to the tallent, It provides great surround sound, but the voices that are critical to your success need quality pick up close to the source and that wont work if you are using say a 100 mm or 85mm lens to get an out of focus background from a distance, even 3m is too far in a lot of cases.
