Wanting

Here is the camera that meets your specifications:

http://www.usa.canon.com/cusa/professional/products/professional_cameras/cinema_eos_cameras/eos_c500

Price starts at $2600 (without lenses).

To get any point and shoot camera with above average "low-light" ability, the price starts at about $400.
And that low-light performance is well below what you want.
