Often, it's tough to picture the difference in sensor sizing purely by researching a spec sheet. The graphic underneath might offer you a stronger sense of the sensor sizes in the 1D X III and 645Z.

As you can see, both cameras feature different megapixels and different sensor sizing. The 1D X III because of its smaller sensor is going to make shooting shallow depth of field trickier and the Pentax 645Z will result in extra detail as a result of its extra 31MP. Higher resolution will enable you to crop photographs way more aggressively. The more recent 1D X III provides a benefit when it comes to sensor technology.
