Panasonic G5 vs Pentax K20D Sensor Comparison

In many cases, it can be tough to visualise the difference in sensor dimensions merely by looking through specifications. The image underneath will help provide you a stronger sense of the sensor sizes in the G5 and K20D.

To sum up, the 2 cameras posses different megapixels and different sensor dimensions. The G5 because of its smaller sensor will make achieving shallower DOF more challenging and the Panasonic G5 will result in extra detail as a result of its extra 1MP. Higher resolution will also let you crop photographs somewhat more aggressively. The newer G5 is going to have an edge when it comes to sensor innovation.
