Ricoh PX vs Sigma DP2 Sensor Comparison

More often than not, it's difficult to imagine the contrast in sensor measurements just by seeing a spec sheet. The graphic below may offer you a more clear sense of the sensor sizes in the PX and DP2.

As you can see, both of those cameras posses different megapixel count and different sensor measurements. The PX featuring a smaller sensor is going to make shooting shallow depth of field tougher and the Ricoh PX will produce extra detail due to its extra 11 Megapixels. Greater resolution will help you crop pics somewhat more aggressively. The more recent PX should have an edge with regard to sensor tech.
