Normally, it is hard to imagine the contrast in sensor dimensions just by going through a spec sheet. The pic here might provide you a greater sense of the sensor sizes in the K-30 and A900.

Clearly, both of these cameras offer different resolutions and different sensor dimensions. The K-30 using its smaller sensor is going to make shooting shallower DOF trickier and the Sony A900 will produce more detail with its extra 9 Megapixels. Greater resolution will also enable you to crop photos a little more aggressively. The more modern K-30 provides an edge with regard to sensor tech.
