Sometimes, it is very difficult to visualise the gap between sensor dimensions only by checking specs. The pic here may give you a far better sense of the sensor sizing in the TG-3 and A3000.

As you can plainly see, both of those cameras have got different megapixels and different sensor dimensions. The TG-3 using its tinier sensor will make getting shallower DOF more difficult and the Sony A3000 will give you extra detail because of its extra 4MP. Higher resolution will make it easier to crop photographs much more aggressively. The younger TG-3 will have a benefit in sensor tech.
