Typically, it is hard to visualise the difference in sensor sizing only by going through a spec sheet. The photograph below might provide you a far better sense of the sensor sizing in the L1 and 645Z.

Clearly, both the cameras come with different megapixels and different sensor sizing. The L1 featuring a smaller sensor will make achieving bokeh harder and the Pentax 645Z will produce greater detail due to its extra 44 Megapixels. Greater resolution will also help you crop images a good deal more aggressively. The older L1 will be disadvantaged when it comes to sensor tech.
