Olympus E-620 vs Pentax K-30 Sensor Comparison

Generally, it's difficult to picture the contrast in sensor dimensions only by looking through technical specs. The pic underneath will help give you a greater sense of the sensor measurements in the E-620 and K-30.

As you have seen, both of those cameras posses different megapixels and different sensor dimensions. The E-620 with its smaller sensor is going to make getting shallow depth of field more difficult and the Pentax K-30 will render greater detail because of its extra 4MP. Greater resolution will make it easier to crop images somewhat more aggressively. The more aged E-620 will be disadvantaged with regard to sensor innovation.
