Usually, it can be tough to imagine the gap in sensor measurements only by checking out specs. The graphic below will provide you a far better sense of the sensor measurements in the DP1s and A7c.

As you can plainly see, both cameras provide different resolutions and different sensor measurements. The DP1s because of its smaller sensor is going to make achieving shallower DOF trickier and the Sony A7c will provide greater detail due to its extra 19 Megapixels. Higher resolution will also allow you to crop pictures more aggressively. The older DP1s will be disadvantaged in sensor tech.
