The E-PL1 was introduced 5 years earlier than the K-S2 which is a fairly serious difference as far as camera tech is concerned. Each of the cameras have different body design with the Olympus E-PL1 being a Rangefinder-style mirrorless camera and the Pentax K-S2 being a Compact SLR camera.

Before getting into a complete comparison, here is a simple introduction of how the E-PL1 scores versus the K-S2 in regards to portability, imaging, features and an overall score.

Usually, it is difficult to picture the gap in sensor sizes only by looking through a spec sheet. The picture underneath will offer you a stronger sense of the sensor measurements in the E-PL1 and K-S2.

Clearly, both cameras have different megapixels and different sensor sizes. The E-PL1 with its smaller sensor is going to make achieving shallower DOF trickier and the Pentax K-S2 will render more detail using its extra 8MP. Higher resolution can also let you crop pictures a bit more aggressively. The more aged E-PL1 will be disadvantaged with regard to sensor technology.
