Both Leica M Typ 240 and Leica Q have 24.0 MP resolution sensors but Leica M Typ 240's sensor is Full frame (36 x 24 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 Leica M Typ 240.
Below you can see the M Typ 240 and Q Typ 116 sensor size comparison.
Leica M Typ 240 and Leica Q have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Leica M Typ 240 and Leica Q sensors have been tested by DxO and the results show that Q Typ 116 has a better overall score of 85, 1 points higher compared to M Typ 240's score of 84.
