Olympus E-400 vs Pentax K-S1 Sensor Comparison

Typically, it's tough to visualize the contrast between sensor dimensions merely by reviewing a spec sheet. The picture here will give you a far better sense of the sensor sizing in the E-400 and K-S1.

As you can see, each of these cameras come with different megapixel count and different sensor dimensions. The E-400 due to its tinier sensor is going to make shooting shallow DOF harder and the Pentax K-S1 will deliver greater detail as a result of its extra 10MP. Greater resolution can also help you crop pics a good deal more aggressively. The more aged E-400 is going to be disadvantaged with regard to sensor tech.
