Sometimes, it is very difficult to picture the difference between sensor measurements just by reading through specifications. The graphic underneath may give you a more clear sense of the sensor sizing in the E-M1 III and S1H.

To sum up, both cameras have different megapixels and different sensor measurements. The E-M1 III using its tinier sensor is going to make achieving shallower depth of field tougher and the Panasonic S1H will give extra detail because of its extra 4MP. Higher resolution can also let you crop pictures a bit more aggressively.
