Quite often, it is difficult to imagine the gap between sensor sizing only by checking specifications. The visual underneath might provide you a greater sense of the sensor dimensions in the X70 and A7R.

Plainly, the 2 cameras offer different resolutions and different sensor sizing. The X70 because of its tinier sensor is going to make getting shallow DOF tougher and the Sony A7R will give you more detail due to its extra 24 Megapixels. Greater resolution will enable you to crop images a little more aggressively. The older X70 is going to be disadvantaged when it comes to sensor innovation.
