To sum up, both the cameras feature different megapixels and different sensor sizing. The ST90 using its tinier sensor is going to make getting shallower depth of field harder and the Sony A3000 will deliver extra detail using its extra 6 Megapixels. Higher resolution will also let you crop shots way more aggressively. The older ST90 is going to be disadvantaged in sensor technology.
