Generally, it is hard to imagine the difference between sensor sizing purely by looking at a spec sheet. The photograph here might provide you a much better sense of the sensor dimensions in the Q10 and G3.

Clearly, the 2 cameras have the same sensor dimensions but different megapixels. You can anticipate the Pentax Q10 to give you greater detail because of its extra 2 Megapixels. Greater resolution will also allow you to crop pics a bit more aggressively. The more recent Q10 should have an advantage when it comes to sensor innovation.
