Leica M10 has a
24.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Maestro II processor. On the other hand, Olympus E-PM2 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor .
Leica M10's sensor provides 8MP more than Olympus E-PM2'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 M10 and E-PM2 sensor size comparison.
As seen above, Leica M10 has a 3.8x Larger sensor area than Olympus E-PM2. 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
Both Leica M10 and Olympus E-PM2 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, M10 has scored 86, 14 points higher than E-PM2.
