Sony RX1 has a
24.0MP Full frame (35.8 x 23.8 mm ) sized CMOS sensor . On the other hand, Ricoh GR has a
16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor .
Sony RX1's sensor provides 8MP more than Ricoh GR'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 RX1 and GR sensor size comparison.
As seen above, Sony RX1 has a 2.3x Larger sensor area than Ricoh GR. 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 Sony RX1 and Ricoh GR 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, RX1 has scored 93, 15 points higher than GR.
