Sony RX100 III has a
20.0MP 1″ (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Leica Q has a
24.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Maestro II processor.
Below you can see the RX100 III and Q Typ 116 sensor size comparison.
As seen above, Leica Q has a 7.4x Larger sensor area than Sony RX100 III. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 RX100 III and Leica Q sensors have been tested by DxO and the results show that Q Typ 116 has a better overall score of 85, 18 points higher compared to RX100 III's score of 67.
