The RX100 is a camera that fits in your jeans pocket. Would I consider intercutting RX100 footage with 1080p from a pro Super 35mm cinema camera? Yes I would.
This camera is the best compact ever created. You simply cannot get more image quality or features into a shirt pocket.
The footage was shot entirely handheld with the optical stabiliser, in 1080/50p 28Mbit AVCHD mode. Lens is the built in Zeiss Vario Sonnar T* 10-37mm F1.8-4.9
