Quite often, its difficult to imagine the contrast in sensor dimensions simply by seeing technical specs. The image underneath should provide you a much better sense of the sensor measurements in the E-M5 III and K-7.

As you have seen, both of the cameras come with different megapixels and different sensor dimensions. The E-M5 III because of its smaller sensor is going to make getting shallow DOF harder and the Olympus E-M5 III will produce extra detail due to its extra 5 Megapixels. Greater resolution will help you crop photos a good deal more aggressively. The more recent E-M5 III provides a benefit when it comes to sensor technology.
