Sony A900 vs Sony RX10 III Sensor Comparison

More often than not, it's difficult to visualize the gap in sensor sizing only by researching a spec sheet. The photograph here might offer you a much better sense of the sensor sizing in the A900 and RX10 III.

Clearly, both the cameras offer different megapixel count and different sensor sizing. The A900 because of its larger sensor is going to make getting bokeh simpler and the Sony A900 will provide you with more detail as a result of its extra 5 Megapixels. Greater resolution can also make it easier to crop photos a little more aggressively. The older A900 will be disadvantaged in sensor technology.
