Panasonic GF2 vs Pentax K-S1 Sensor Comparison

Sometimes, its tough to imagine the difference between sensor measurements simply by reviewing a spec sheet. The photograph below might give you a much better sense of the sensor sizes in the GF2 and K-S1.

As you can see, both of those cameras provide different megapixels and different sensor measurements. The GF2 using its tinier sensor is going to make achieving shallow DOF more challenging and the Pentax K-S1 will offer more detail using its extra 8 Megapixels. Greater resolution can also enable you to crop pics more aggressively. The older GF2 is going to be disadvantaged when it comes to sensor tech.
