Sony RX1R has a 24.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor . On the other hand, Leica Q2 has a 47.0MP Full frame (36 x 24 mm ) sized CMOS sensor .
Leica Q2's sensor provides 23MP more than Sony RX1R's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Another similarity between these two cameras is that both Leica Q2 and Sony RX1R sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.
Below you can see the RX1R and Q2 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony RX1R and Leica Q2 Cameras
Sony RX1R and Leica Q2 have almost the same sensor size so none of them has any significant advantage over other in providing control over 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. Sony RX1R and Leica Q2 sensors have been tested by DxO and the results show that Q2 has a better overall score of 96, 5 points higher compared to RX1R's score of 91.
