Ricoh WG-4 vs Sigma DP2x Sensor Comparison

Typically, its hard to envision the difference in sensor dimensions only by checking out a spec sheet. The picture underneath should offer you a clearer sense of the sensor sizing in the WG-4 and DP2x.

Clearly, each of these cameras feature different resolutions and different sensor dimensions. The WG-4 using its smaller sensor will make shooting shallow depth of field more challenging and the Ricoh WG-4 will provide extra detail using its extra 11 Megapixels. Higher resolution will let you crop photographs way more aggressively. The more recent WG-4 is going to have an edge with regard to sensor innovation.
