Plainly, the two cameras have got different megapixels and different sensor dimensions. The TG-3 featuring a smaller sensor is going to make getting shallow DOF harder and the Sony A7c will provide extra detail as a result of its extra 8 Megapixels. Greater resolution will also let you crop pics much more aggressively. The more aged TG-3 will be behind with regard to sensor tech.
