Typically, it's tough to visualize the difference in sensor sizes just by seeing specs. The image underneath might provide you a greater sense of the sensor sizing in the 1Ds and 645Z.

As you can plainly see, both cameras enjoy different resolutions and different sensor sizes. The 1Ds due to its smaller sensor is going to make getting shallow DOF harder and the Pentax 645Z will produce extra detail as a result of its extra 40 Megapixels. Higher resolution will allow you to crop pictures far more aggressively. The more aged 1Ds will be behind when it comes to sensor innovation.
