Olympus E-1 vs Pentax K10D Sensor Comparison

Typically, it is tough to see the gap between sensor dimensions just by looking at specifications. The picture here will help give you a much better sense of the sensor sizes in the E-1 and K10D.

Plainly, the two cameras provide different resolutions and different sensor dimensions. The E-1 featuring a tinier sensor will make getting shallower depth of field trickier and the Pentax K10D will resolve greater detail as a result of its extra 5 Megapixels. Higher resolution will also let you crop pictures more aggressively. The more aged E-1 is going to be disadvantaged in sensor technology.
