More often than not, it can be difficult to visualise the gap between sensor dimensions simply by reviewing a spec sheet. The picture below will help offer you a greater sense of the sensor sizes in the E-P1 and A77 II.

Clearly, each of the cameras come with different megapixels and different sensor dimensions. The E-P1 using its tinier sensor will make shooting shallower depth of field tougher and the Sony A77 II will offer extra detail using its extra 12 Megapixels. Higher resolution will let you crop photographs a good deal more aggressively. The more aged E-P1 is going to be disadvantaged in sensor tech.
