Generally, it is very hard to imagine the gap between sensor sizing simply by reading through specifications. The visual here will help offer you a clearer sense of the sensor sizing in the E-30 and A58.

Plainly, both the cameras offer different megapixels and different sensor sizing. The E-30 due to its tinier sensor is going to make shooting shallow depth of field more challenging and the Sony A58 will give you extra detail having its extra 8 Megapixels. Greater resolution will also help you crop images a little more aggressively. The older E-30 is going to be behind in sensor innovation.
