Olympus E-3 has a
10.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic III processor. 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-3 and E-5 sensor size comparison.
Olympus E-3 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-3 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.
