Generally, it's hard to see the contrast in sensor measurements only by going through a spec sheet. The graphic below will provide you a clearer sense of the sensor measurements in the OM System OM-1 and S5 II X.

Clearly, both cameras enjoy different megapixels and different sensor measurements. The OM System OM-1 due to its smaller sensor will make getting shallower DOF more difficult and the Panasonic S5 II X will produce greater detail having its extra 4 Megapixels. Greater resolution can also make it easier to crop photos far more aggressively. The older OM System OM-1 will be behind in sensor tech.
