As you can tell, both the cameras feature different megapixel count and different sensor measurements. The T900 with its smaller sensor is going to make getting shallower DOF more difficult and the Sony A55 will render more detail because of its extra 4MP. Greater resolution will allow you to crop photos way more aggressively. The older T900 will be disadvantaged with regard to sensor technology.
