Panasonic G1 vs Pentax K-5 Sensor Comparison

More often than not, it is tough to envision the difference in sensor sizes simply by checking out a spec sheet. The picture here may provide you a more clear sense of the sensor sizing in the G1 and K-5.

Clearly, both cameras provide different resolutions and different sensor sizes. The G1 with its smaller sensor will make achieving shallower DOF trickier and the Pentax K-5 will produce more detail with its extra 4MP. Greater resolution will also make it easier to crop pics more aggressively. The more aged G1 will be behind when it comes to sensor tech.
