Olympus E-520 has a
10.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Olympus E-30 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic III+ processor.
Below you can see the E-520 and E-30 sensor size comparison.
Olympus E-520 and Olympus E-30 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 compared to Olympus E-30, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
