Normally, it can be difficult to visualise the gap in sensor sizing merely by going through a spec sheet. The graphic here should give you a much better sense of the sensor dimensions in the ST90 and A58.

Clearly, both of those cameras feature different megapixel count and different sensor sizing. The ST90 featuring a smaller sensor will make getting shallower DOF trickier and the Sony A58 will show more detail due to its extra 6MP. Higher resolution can also make it easier to crop pictures way more aggressively. The older ST90 will be disadvantaged when it comes to sensor tech.
