Olympus E-620 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-520 has a
10.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor .
Below you can see the E-620 and E-520 sensor size comparison.
Olympus E-620 and Olympus E-520 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-520 has 22% larger pixel area (22.54µm2 vs 18.45µm2) compared to Olympus E-620, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
At Camera Decision, we also look at Dxo Mark sensors when available as we think it is a good indicator of image quality.
