As you can see, both cameras come with different resolutions and different sensor measurements. The A850 using its larger sensor is going to make shooting shallower depth of field less difficult and the Sony A850 will give you extra detail because of its extra 15MP. Greater resolution can also make it easier to crop photos a good deal more aggressively. The newer A850 should have an advantage in sensor technology.
