To sum up, both cameras enjoy different resolutions and different sensor dimensions. The A33 due to its tinier sensor is going to make getting shallower DOF more difficult and the Sony A99 will deliver extra detail as a result of its extra 10MP. Higher resolution can also help you crop shots far more aggressively. The more aged A33 is going to be disadvantaged in sensor technology.
