Panasonic GF5 vs Pentax K20D Sensor Comparison

Oftentimes, its hard to see the difference in sensor sizing only by seeing a spec sheet. The graphic below might give you a better sense of the sensor dimensions in the GF5 and K20D.

As you can see, both of the cameras offer different resolutions and different sensor sizing. The GF5 featuring a smaller sensor will make achieving shallow depth of field trickier and the Pentax K20D will provide more detail due to its extra 3 Megapixels. Greater resolution will enable you to crop pics a little more aggressively. The fresher GF5 will have a benefit with regard to sensor innovation.
