Typically, it is tough to envision the contrast in sensor measurements purely by going through specifications. The photograph here will offer you a much better sense of the sensor measurements in the FX78 and K-3.

Plainly, the 2 cameras offer different megapixel count and different sensor measurements. The FX78 having a smaller sensor will make achieving shallow DOF more difficult and the Pentax K-3 will provide greater detail with its extra 12MP. Higher resolution will also let you crop photographs a little more aggressively. The older FX78 will be disadvantaged when it comes to sensor technology.
