According to the latest rumor surfaced over the web the Sony is selling its Rx100 M3 sensor to Fujfilm, Panasonic and Samsung, now we need no further proof to understand from where the Fuji FZ1000 sensor camera from…however due to Panasonic advance technology and fast image processor they are able take out 4K video from the same sensor 🙂
It is also possible that the upcoming Fujifilm X 30 camera may feature same 1 inch sensor as the RX100 M3 camera.
If you have some time – you can see the specification and image comparison between the FZ1000 and RX10 here
