Typically, it's hard to imagine the contrast in sensor dimensions merely by seeing specifications. The pic below might provide you a greater sense of the sensor sizing in the DP1s and A900.

Plainly, both of those cameras posses different resolutions and different sensor dimensions. The DP1s using its smaller sensor is going to make getting shallower depth of field trickier and the Sony A900 will provide more detail using its extra 20 Megapixels. Greater resolution will also help you crop pics somewhat more aggressively. The more modern DP1s provides an edge with regard to sensor technology.
