Pentax WG-3 vs Sony NEX-3 Sensor Comparison

Normally, its difficult to picture the gap in sensor sizes simply by researching specs. The pic here should offer you a more clear sense of the sensor sizes in the WG-3 and NEX-3.

All in all, both of the cameras posses different resolutions and different sensor sizes. The WG-3 featuring a smaller sensor is going to make shooting shallower depth of field tougher and the Pentax WG-3 will provide you with more detail having its extra 2MP. Greater resolution will also let you crop photos somewhat more aggressively. The newer WG-3 should have an advantage when it comes to sensor innovation.
