Grace, rest assured this is an amazing little camera for stock footage. I own it, as well as the GX80.
The point about low light is valid but at the end of the day, don't try and specialise in footage that needs to be shot in the dark! That said, there are workarounds and footage is usable with pretty high ISO's.
In my opinion there isn't another camera with these specs and ability for anything like the money.
Happy shooting.
