Pentax WG-2 GPS vs Sony A580 Sensor Comparison

          

          

            
Generally, it is hard to see the gap in sensor dimensions simply by checking out a spec sheet. The image underneath might offer you a stronger sense of the sensor sizing in the WG-2 GPS and A580.
Clearly, each of the cameras offer the same exact MP but not the same sensor dimensions. The WG-2 GPS contains the smaller sensor which will make getting bokeh trickier. The more recent WG-2 GPS is going to have an advantage in sensor tech.
