More often than not, it can be hard to imagine the contrast between sensor dimensions only by reading specs. The image here will help provide you a greater sense of the sensor dimensions in the E-P3 and K-5 IIs.

As you can plainly see, the 2 cameras enjoy different resolutions and different sensor dimensions. The E-P3 having a tinier sensor is going to make getting bokeh more difficult and the Pentax K-5 IIs will offer greater detail because of its extra 4 Megapixels. Higher resolution can also let you crop pictures far more aggressively. The more aged E-P3 is going to be disadvantaged in sensor innovation.
