Panasonic G2 vs Pentax K100D Sensor Comparison

Often, it can be tough to imagine the gap between sensor measurements simply by going over technical specs. The visual underneath may provide you a far better sense of the sensor measurements in the G2 and K100D.

As you can tell, both of those cameras enjoy different megapixels and different sensor measurements. The G2 because of its tinier sensor is going to make shooting shallower DOF more challenging and the Panasonic G2 will offer greater detail as a result of its extra 6MP. Greater resolution will also let you crop pics far more aggressively. The more recent G2 should have a benefit in sensor technology.
