Normally, it is very hard to visualize the contrast between sensor sizes only by going over a spec sheet. The picture underneath will help provide you a far better sense of the sensor sizes in the E-M1 III and ZS45.

Clearly, both of these cameras come with different megapixels and different sensor sizes. The E-M1 III featuring a bigger sensor is going to make getting shallow depth of field easier and the Olympus E-M1 III will offer extra detail having its extra 4MP. Higher resolution will make it easier to crop shots a good deal more aggressively. The younger E-M1 III should have a benefit with regard to sensor innovation.
