The E-PL1s was announced 5 years prior to the K-S2 which is quite a serious gap as far as tech is concerned. Both the cameras offer different body type with the Olympus E-PL1s being a Rangefinder-style mirrorless camera and the Pentax K-S2 being a Compact SLR camera.

Before going in to a full comparison, below is a concise introduction of how the E-PL1s scores against the K-S2 when considering portability, imaging, features and an overall score.

Often, it is very tough to envision the contrast between sensor sizes only by looking at specs. The pic underneath might offer you a much better sense of the sensor dimensions in the E-PL1s and K-S2.

All in all, both of these cameras offer different megapixels and different sensor sizes. The E-PL1s using its tinier sensor will make shooting shallow depth of field more challenging and the Pentax K-S2 will resolve more detail with its extra 8MP. Greater resolution will let you crop images a little more aggressively. The more aged E-PL1s is going to be disadvantaged in sensor innovation.
