Typically, it is difficult to visualize the difference in sensor measurements merely by looking through technical specs. The photograph underneath should offer you a better sense of the sensor sizing in the FE-4000 and 645Z.

As you have seen, both cameras posses different megapixel count and different sensor measurements. The FE-4000 because of its smaller sensor is going to make shooting shallow DOF more challenging and the Pentax 645Z will result in extra detail due to its extra 39MP. Higher resolution will also allow you to crop shots somewhat more aggressively. The older FE-4000 will be behind with regard to sensor innovation.
