I need a high quality video camera that supports 16:9 1080p recording with at least an 10mpx lenses. It must have auto-focusing and/or manual focusing, including zooming. It also must have the ability to record screen (light adjustment). It also need an acceptable audio quality or to have an microphone jack. I will not buy the camera right now but I will not pay more that 500$. What video camera should I buy?
