Olympus 550WP vs Pentax Q-S1 Sensor Comparison

Quite often, it's difficult to visualize the gap in sensor measurements just by looking through technical specs. The graphic here might provide you a much better sense of the sensor dimensions in the 550WP and Q-S1.

As you have seen, both of those cameras offer different megapixels and different sensor measurements. The 550WP having a smaller sensor is going to make getting shallower DOF tougher and the Pentax Q-S1 will provide you with greater detail having an extra 2MP. Higher resolution will also allow you to crop pictures a little more aggressively. The older 550WP will be disadvantaged with regard to sensor innovation.
