Olympus E-450 vs Pentax K100D S Sensor Comparison

Normally, it is very hard to imagine the contrast between sensor dimensions merely by reading through specs. The picture here may give you a stronger sense of the sensor dimensions in the E-450 and K100D S.

All in all, both of these cameras enjoy different megapixels and different sensor dimensions. The E-450 because of its tinier sensor is going to make shooting shallower DOF tougher and the Olympus E-450 will give extra detail due to its extra 4MP. Higher resolution will also make it easier to crop photographs far more aggressively. The more modern E-450 should have an edge with regard to sensor tech.
