Panasonic G5 vs Pentax K-x Sensor Comparison

Oftentimes, it can be tough to imagine the gap in sensor dimensions merely by seeing technical specs. The image underneath will help provide you a much better sense of the sensor dimensions in the G5 and K-x.

As you can tell, each of the cameras posses different megapixels and different sensor dimensions. The G5 using its smaller sensor is going to make achieving shallow depth of field tougher and the Panasonic G5 will produce more detail using its extra 4MP. Higher resolution can also let you crop shots somewhat more aggressively. The newer G5 should have an advantage when it comes to sensor innovation.
