As you have seen, both cameras offer different megapixels and different sensor measurements. The E-620 using its tinier sensor will make getting shallow DOF more difficult and the Pentax K-01 will offer you greater detail with its extra 4MP. Greater resolution can also enable you to crop photos a little more aggressively. The older E-620 is going to be behind when it comes to sensor innovation.
