Olympus E-620 vs Pentax K100D S Sensor Comparison

Generally, it's tough to picture the contrast between sensor dimensions purely by going over specs. The image below will give you a better sense of the sensor sizes in the E-620 and K100D S.

All in all, the two cameras posses different resolutions and different sensor dimensions. The E-620 due to its tinier sensor is going to make shooting shallow depth of field harder and the Olympus E-620 will offer extra detail as a result of its extra 6 Megapixels. Higher resolution can also help you crop photographs somewhat more aggressively. The younger E-620 provides an advantage with regard to sensor technology.
