Often, it's difficult to visualize the contrast between sensor sizing only by reading a spec sheet. The visual here will help give you a more clear sense of the sensor dimensions in the E-P3 and A900.

As you can see, both of those cameras provide different resolutions and different sensor sizing. The E-P3 having a tinier sensor is going to make shooting bokeh more difficult and the Sony A900 will offer you greater detail using its extra 13 Megapixels. Greater resolution will let you crop photos more aggressively. The newer E-P3 provides an edge when it comes to sensor tech.
