Olympus E-600 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic III+ processor. On the other hand, Olympus E-420 has a
10.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic III processor.
Below you can see the E-600 and E-420 sensor size comparison.
Olympus E-600 and Olympus E-420 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Olympus E-420 has 22% larger pixel area (22.54µm2 vs 18.45µm2) compared to Olympus E-600, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
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 E-600 and Olympus E-420 sensors have been tested by DxO and the results show that E-420 has a better overall score of 56, 1 points higher compared to E-600's score of 55.
