Normally, it is hard to see the contrast between sensor sizing merely by reading a spec sheet. The visual underneath will provide you a far better sense of the sensor measurements in the 645Z and K-500.

Clearly, the two cameras feature different resolutions and different sensor sizing. The 645Z because of its bigger sensor will make getting shallow DOF simpler and the Pentax 645Z will offer you extra detail having its extra 35MP. Higher resolution will enable you to crop photographs way more aggressively.
