Quite often, it is tough to see the gap in sensor sizing just by going through a spec sheet. The graphic below should offer you a better sense of the sensor sizing in the K100D and A35.
Clearly, the two cameras offer the same exact sensor sizing but not the same megapixels. You can anticipate the Sony A35 to provide extra detail because of its extra 10MP. Greater resolution will make it easier to crop pics a little more aggressively. The older K100D will be disadvantaged with regard to sensor tech.
