Oftentimes, it can be difficult to visualise the difference in sensor sizing simply by seeing specifications. The visual below may provide you a far better sense of the sensor dimensions in the fp and a5100.

Plainly, each of the cameras come with different resolutions and different sensor sizing. The fp with its bigger sensor will make getting shallower DOF less difficult and the Sigma fp will show greater detail with its extra 1 Megapixels. Higher resolution will help you crop photographs a good deal more aggressively. The fresher fp will have an advantage with regard to sensor tech.
