Sony EX1R

I am putting together an UAV to shoot HD video. I want thecamera to have many professional qualities but unfortunately I have a weight limit.Therefore I have to settle with what is completely required. These specs are:

Full HD resolution, preferably with interchangeable lenses

10X Optical Zoom minimum

Finally, a way to control the zoom remotely and wirelesslyand if possible other camera functions.

Audio is needed or even a recorder which I can plug externally.
