Typically, it's hard to picture the difference between sensor measurements purely by reading specs. The graphic here should provide you a more clear sense of the sensor dimensions in the E-M5 II and NEX-5.

All in all, each of the cameras have different megapixel count and different sensor measurements. The E-M5 II using its tinier sensor is going to make shooting bokeh harder and the Olympus E-M5 II will deliver more detail with its extra 2MP. Greater resolution will make it easier to crop photos a bit more aggressively. The newer E-M5 II should have an edge with regard to sensor tech.
