Sometimes, it is hard to visualize the gap between sensor dimensions only by reading through a spec sheet. The picture here will help give you a stronger sense of the sensor measurements in the E-PL1 and A7 III.

Clearly, both of the cameras have different megapixel count and different sensor dimensions. The E-PL1 featuring a tinier sensor is going to make shooting shallower DOF more difficult and the Sony A7 III will give more detail as a result of its extra 12 Megapixels. Greater resolution will also allow you to crop pics a bit more aggressively. The more aged E-PL1 is going to be behind with regard to sensor innovation.
