Olympus XZ-2 iHS has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor . On the other hand, Panasonic LX10 has a
20.0MP 1″ (13.2 x 8.8 mm ) sized BSI-CMOS sensor .
Panasonic LX10's sensor provides 8MP more than Olympus XZ-2 iHS'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.
Below you can see the XZ-2 iHS and LX10 sensor size comparison.
As seen above, Panasonic LX10 has a 2.8x Larger sensor area than Olympus XZ-2 iHS. 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. Olympus XZ-2 iHS and Panasonic LX10 sensors have been tested by DxO and the results show that LX10 has a better overall score of 70, 21 points higher compared to XZ-2 iHS's score of 49.
