To sum up, both of the cameras have different megapixel count and different sensor dimensions. The FS25 with its smaller sensor is going to make getting shallow depth of field harder and the Pentax K20D will provide more detail with its extra 3 Megapixels. Greater resolution will also make it easier to crop pics a bit more aggressively. The more modern FS25 provides an edge with regard to sensor technology.
