The E-330 was brought out 3 years earlier than the K20D which is quite a serious difference as far as technology is concerned. Both of the cameras feature the same body design (Mid-size SLR).

Before we go right into a in depth comparison, here is a simple summary of how the E-330 matches up against the K20D with respect to portability, imaging, features and an overall score.

Here is a preview of the gallery images for Olympus E-330 & Pentax K20D. The entire galleries are viewable at Olympus E-330 Gallery & Pentax K20D Gallery.

When you are aiming to carry around your camera frequently, you will want to factor its weight and dimensions.

Quite often, it is very hard to picture the gap between sensor sizes simply by reading specifications. The picture here should provide you a much better sense of the sensor dimensions in the E-330 and K20D.

To sum up, the 2 cameras come with different megapixels and different sensor sizes. The E-330 featuring a tinier sensor is going to make achieving shallow depth of field trickier and the Pentax K20D will deliver extra detail having its extra 8 Megapixels. Higher resolution will also make it easier to crop shots a good deal more aggressively. The more aged E-330 is going to be disadvantaged with regard to sensor technology.
