Olympus SP-565UZ vs Pentax K20D Sensor Comparison

Normally, it is difficult to picture the difference in sensor measurements only by looking through specs. The visual underneath may offer you a clearer sense of the sensor sizing in the SP-565UZ and K20D.

As you can plainly see, both of those cameras posses different megapixels and different sensor measurements. The SP-565UZ with its smaller sensor is going to make getting shallow DOF more difficult and the Pentax K20D will result in greater detail with its extra 5 Megapixels. Greater resolution will allow you to crop images somewhat more aggressively. The younger SP-565UZ should have a benefit when it comes to sensor technology.
