Olympus E-400 vs Pentax I-10 Sensor Comparison

Clearly, the two cameras enjoy different megapixel count and different sensor sizes. The E-400 featuring a larger sensor is going to make shooting shallow DOF less difficult and the Pentax I-10 will give you greater detail having its extra 2 Megapixels. Greater resolution can also enable you to crop pics far more aggressively. The more aged E-400 is going to be behind when it comes to sensor technology.
