Ricoh CX1 vs Sigma DP2s Sensor Comparison

In many cases, its hard to imagine the contrast in sensor dimensions purely by seeing specs. The picture underneath might offer you a better sense of the sensor sizing in the CX1 and DP2s.

All in all, both of these cameras posses different megapixel count and different sensor dimensions. The CX1 due to its smaller sensor is going to make getting shallower DOF harder and the Ricoh CX1 will show more detail having its extra 4MP. Higher resolution will also make it easier to crop photographs somewhat more aggressively. The more aged CX1 will be disadvantaged in sensor technology.
