Sometimes, it's tough to imagine the gap between sensor sizes purely by checking specs. The picture below will help give you a far better sense of the sensor dimensions in the 7000 and 645Z.

All in all, both of those cameras have got different resolutions and different sensor sizes. The 7000 having a tinier sensor is going to make achieving shallow depth of field trickier and the Pentax 645Z will give you more detail with its extra 39 Megapixels. Higher resolution will let you crop photographs much more aggressively. The more aged 7000 is going to be behind in sensor technology.
