Normally, it is very tough to visualise the difference between sensor dimensions merely by looking at technical specs. The picture here may give you a more clear sense of the sensor sizes in the E-PL2 and A7 III.

As you can tell, the 2 cameras provide different megapixels and different sensor dimensions. The E-PL2 using its tinier sensor will make achieving shallower depth of field harder and the Sony A7 III will give you extra detail using its extra 12MP. Greater resolution will enable you to crop images more aggressively. The more aged E-PL2 is going to be behind in sensor technology.
