Typically, it can be difficult to visualise the difference in sensor sizing merely by researching a spec sheet. The photograph underneath will offer you a far better sense of the sensor dimensions in the E-P3 and H400.

Clearly, both of these cameras provide different megapixel count and different sensor sizing. The E-P3 because of its larger sensor will make getting shallower depth of field less difficult and the Sony H400 will result in extra detail as a result of its extra 8MP. Greater resolution will also enable you to crop pics more aggressively. The older E-P3 will be disadvantaged with regard to sensor innovation.
