Olympus E-510 has a
10.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Olympus E-5 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic V+ processor.
Below you can see the E-510 and E-5 sensor size comparison.
Olympus E-510 and Olympus E-5 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-510 has 22% larger pixel area compared to Olympus E-5, it has potential to collect more light on pixel level hence 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-510 and Olympus E-5 sensors have been tested by DxO and the results show that E-5 has a better overall score of 56, 4 points higher compared to E-510's score of 52.
