Plainly, both of the cameras come with different resolutions and different sensor measurements. The EX-S7 with its smaller sensor is going to make achieving shallower depth of field more difficult and the Samsung NX20 will provide you with greater detail using its extra 8 Megapixels. Higher resolution will also let you crop photographs a good deal more aggressively. The older EX-S7 will be disadvantaged when it comes to sensor tech.
