Olympus E-510 vs Pentax K100D Sensor Comparison

Sometimes, it can be tough to visualize the gap between sensor sizing merely by reviewing technical specs. The graphic below will provide you a far better sense of the sensor dimensions in the E-510 and K100D.

As you can tell, both cameras offer different megapixels and different sensor sizing. The E-510 using its tinier sensor is going to make shooting shallow depth of field tougher and the Olympus E-510 will deliver greater detail because of its extra 4MP. Greater resolution can also enable you to crop photos a little more aggressively. The more recent E-510 provides an advantage when it comes to sensor technology.
