Normally, its tough to visualize the contrast in sensor sizing simply by seeing a spec sheet. The visual underneath will help offer you a better sense of the sensor dimensions in the S1 and Q7.

As you can see, both the cameras provide different megapixel count and different sensor sizing. The S1 having a smaller sensor is going to make achieving shallow DOF more challenging and the Pentax S1 will provide greater detail using its extra 2 Megapixels. Greater resolution can also help you crop photos more aggressively. The older S1 will be behind with regard to sensor tech.
