Panasonic GH1 vs Pentax RZ18 Sensor Comparison

Oftentimes, its tough to envision the difference between sensor sizing purely by checking a spec sheet. The photograph below should provide you a much better sense of the sensor sizes in the GH1 and RZ18.

Clearly, both the cameras provide different resolutions and different sensor sizing. The GH1 because of its bigger sensor will make achieving shallower DOF easier and the Pentax RZ18 will resolve extra detail as a result of its extra 4MP. Higher resolution will also make it easier to crop photographs more aggressively. The older GH1 is going to be disadvantaged in sensor technology.
