All in all, both of those cameras enjoy different megapixel count and different sensor measurements. The E-330 with its smaller sensor will make achieving shallow DOF harder and the Sony A55 will produce extra detail because of its extra 9MP. Higher resolution will enable you to crop shots far more aggressively. The older E-330 will be disadvantaged when it comes to sensor tech.
