Both Sony RX1 and Leica Q have 24.0 MP resolution sensors but Sony RX1's sensor is Full frame (35.8 x 23.8 mm ) and Leica Q's sensor is Full frame (36 x 24 mm ).
Since Leica Q's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Sony RX1.
Below you can see the RX1 and Q Typ 116 sensor size comparison.
Sony RX1 and Leica Q have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
Both Sony RX1 and Leica Q sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, RX1 has scored 93, 8 points higher than Q Typ 116.
