(Compact cameras are mirrorless indeed, but they do not take interchangeable lenses so they might deserve a type of their own.)  Model listed both as "DSC-RX100M2" and just "RX100 II"  in Sony sources, and also as "RX100II" elsewhere.  A compact camera with a 1" Sony CMOS sensor with Exmor-R technology, 5472 x 3648 pixels of 2.40 μm size; one of the IMX183 family if I am not mistaken. Lens: Carl Zeiss Vario Sonnar T* 1.8-4.9 / 10.4-37.1 mm.
