Ricoh PX vs Samsung NX20 Sensor Comparison

Typically, it can be difficult to visualise the contrast between sensor sizing only by reading through technical specs. The photograph underneath might provide you a greater sense of the sensor sizes in the PX and NX20.

As you can tell, both cameras provide different resolutions and different sensor sizing. The PX because of its tinier sensor will make achieving shallow depth of field tougher and the Samsung NX20 will give more detail due to its extra 4MP. Greater resolution can also allow you to crop photos more aggressively. The older PX is going to be disadvantaged with regard to sensor technology.
