Ricoh PX vs Sony A7S Sensor Comparison

Usually, it is hard to see the contrast between sensor sizing just by reading through specs. The graphic here might provide you a far better sense of the sensor sizes in the PX and A7S.

As you can plainly see, both of those cameras provide different megapixel count and different sensor sizing. The PX due to its tinier sensor will make getting shallow depth of field more challenging and the Ricoh PX will give greater detail as a result of its extra 4 Megapixels. Higher resolution will let you crop photographs more aggressively. The older PX is going to be disadvantaged when it comes to sensor innovation.
