Typically, it is very difficult to visualize the contrast in sensor sizing only by researching specifications. The graphic below will provide you a stronger sense of the sensor sizing in the 9000 and 645Z.

Plainly, both of those cameras have different megapixel count and different sensor sizing. The 9000 using its smaller sensor is going to make shooting shallow depth of field more difficult and the Pentax 645Z will provide you with greater detail because of its extra 39 Megapixels. Greater resolution can also make it easier to crop images a bit more aggressively. The older 9000 will be behind in sensor tech.
