Olympus SP-100 vs Pentax K20D Sensor Comparison

Usually, it is very difficult to see the difference in sensor sizing only by going through a spec sheet. The photograph below will provide you a better sense of the sensor measurements in the SP-100 and K20D.

As you can see, the 2 cameras feature different megapixel count and different sensor sizing. The SP-100 because of its smaller sensor will make achieving shallow depth of field trickier and the Olympus SP-100 will provide extra detail having its extra 1MP. Greater resolution can also enable you to crop photos way more aggressively. The newer SP-100 is going to have an edge in sensor technology.
