Normally, it's difficult to imagine the gap in sensor sizes purely by seeing specs. The pic here will help give you a more clear sense of the sensor sizes in the K10D and A7c.
All in all, both of the cameras feature different megapixel count and different sensor sizes. The K10D featuring a smaller sensor is going to make getting shallow DOF harder and the Sony A7c will produce greater detail as a result of its extra 14MP. Higher resolution will enable you to crop pictures way more aggressively. The more aged K10D will be behind in sensor innovation.
