Normally, it can be tough to visualize the difference between sensor sizing merely by checking a spec sheet. The photograph below will offer you a stronger sense of the sensor measurements in the SZ-11 and 645Z.

As you can see, the 2 cameras posses different megapixels and different sensor sizing. The SZ-11 with its tinier sensor is going to make achieving shallower depth of field more challenging and the Pentax 645Z will resolve greater detail because of its extra 37 Megapixels. Higher resolution can also help you crop pictures somewhat more aggressively. The older SZ-11 is going to be disadvantaged when it comes to sensor tech.
