The E-510 was manufactured 8 years prior to the K-S2 and that is quite a sizable difference as far as tech is concerned. Each of the cameras have different body design with the Olympus E-510 being a Mid-size SLR camera and the Pentax K-S2 being a Compact SLR camera.

Before we go straight to a in depth comparison, here is a brief summation of how the E-510 grades versus the K-S2 with respect to portability, imaging, features and an overall grade.

Often, its difficult to picture the contrast between sensor measurements merely by reading through specifications. The visual here will help provide you a clearer sense of the sensor sizes in the E-510 and K-S2.

Plainly, both of the cameras have different megapixels and different sensor measurements. The E-510 featuring a tinier sensor is going to make achieving shallow DOF more difficult and the Pentax K-S2 will resolve more detail due to its extra 10MP. Higher resolution will also make it easier to crop pictures a bit more aggressively. The older E-510 is going to be disadvantaged when it comes to sensor technology.
