Clearly, both of the cameras posses different megapixels and different sensor sizes. The A900 because of its larger sensor will make getting shallow depth of field easier and the Sony A900 will offer greater detail as a result of its extra 1MP. Greater resolution can also help you crop photos somewhat more aggressively. The more aged A900 is going to be disadvantaged with regard to sensor tech.
