Ricoh CX3 vs Sigma DP2s Sensor Comparison

Generally, it is tough to visualize the difference in sensor measurements merely by checking out technical specs. The visual underneath might give you a much better sense of the sensor sizes in the CX3 and DP2s.

As you can tell, both the cameras come with different megapixel count and different sensor measurements. The CX3 having a smaller sensor is going to make achieving shallower DOF trickier and the Ricoh CX3 will provide extra detail using its extra 5MP. Higher resolution will also help you crop pictures a good deal more aggressively.
