As you can tell, each of these cameras offer different megapixel count and different sensor measurements. The E-30 featuring a tinier sensor is going to make achieving shallow depth of field more challenging and the Pentax 645Z will deliver greater detail having its extra 39 Megapixels. Higher resolution will also allow you to crop photographs a little more aggressively. The older E-30 is going to be disadvantaged in sensor innovation.
