Panasonic GF1 vs Pentax K100D Sensor Comparison

Oftentimes, it is very difficult to picture the difference in sensor dimensions just by researching a spec sheet. The image underneath should provide you a much better sense of the sensor dimensions in the GF1 and K100D.

Clearly, the 2 cameras posses different megapixels and different sensor dimensions. The GF1 having a smaller sensor is going to make getting shallower DOF more difficult and the Panasonic GF1 will provide you with extra detail because of its extra 6 Megapixels. Higher resolution will let you crop pictures somewhat more aggressively. The younger GF1 should have an edge in sensor technology.
