Quite often, it is very difficult to visualize the difference between sensor sizing only by reading specifications. The graphic below should give you a much better sense of the sensor dimensions in the OM System OM-1 and NX100.

Plainly, both the cameras provide different megapixel count and different sensor sizing. The OM System OM-1 with its tinier sensor is going to make getting shallower DOF harder and the OM System OM-1 will deliver more detail with its extra 5 Megapixels. Greater resolution can also make it easier to crop photos more aggressively. The more recent OM System OM-1 should have a benefit in sensor technology.
