The E-P3 was introduced 14 months earlier than the K-30 making them a generation apart from one another. Both of the cameras have different body design with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Pentax K-30 being a Mid-size SLR camera.

Before delving straight to a in-depth comparison, here is a short introduction of how the E-P3 matches up against the K-30 with regards to portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Olympus PEN E-P3 & Pentax K-30. The whole galleries are viewable at Olympus E-P3 Gallery & Pentax K-30 Gallery.

Normally, it's hard to picture the contrast between sensor measurements purely by reading specifications. The photograph here may offer you a stronger sense of the sensor sizes in the E-P3 and K-30.

Plainly, the two cameras have different resolutions and different sensor measurements. The E-P3 with its tinier sensor is going to make getting bokeh trickier and the Pentax K-30 will offer you more detail using its extra 4MP. Greater resolution can also allow you to crop images a bit more aggressively. The older E-P3 is going to be disadvantaged in sensor innovation.
