In many cases, it's hard to visualise the gap in sensor sizing purely by viewing a spec sheet. The graphic here may offer you a greater sense of the sensor sizing in the K100D S and NEX-3N.

Clearly, both cameras offer the same exact sensor sizing but not the same resolution. You can expect to see the Sony NEX-3N to result in more detail because of its extra 10 Megapixels. Greater resolution can also enable you to crop photos a little more aggressively. The older K100D S will be disadvantaged when it comes to sensor innovation.
