All in all, both of these cameras come with different megapixels and different sensor sizes. The 1s having a bigger sensor will make getting shallower depth of field simpler and the Olympus 1s will resolve more detail using its extra 2MP. Higher resolution can also let you crop photographs a good deal more aggressively. The more modern 1s is going to have a benefit with regard to sensor tech.
