Nikon S31 vs Ricoh PX Sensor Comparison

Sometimes, it is very hard to visualise the gap between sensor sizing purely by checking specs. The visual here should offer you a far better sense of the sensor sizing in the S31 and PX.

As you can plainly see, both of those cameras have different resolutions and different sensor sizing. The S31 having a tinier sensor will make shooting shallow depth of field tougher and the Ricoh PX will give greater detail having an extra 6 Megapixels. Higher resolution will let you crop shots a bit more aggressively. The younger S31 will have a benefit with regard to sensor innovation.
