Sometimes, it's difficult to visualise the contrast in sensor sizing merely by looking through technical specs. The graphic underneath may offer you a clearer sense of the sensor sizing in the E-M10 III and A290.

As you can tell, both of these cameras come with different resolutions and different sensor sizing. The E-M10 III with its smaller sensor will make achieving shallower DOF more challenging and the Olympus E-M10 III will provide you with extra detail because of its extra 2MP. Higher resolution can also make it easier to crop pictures a good deal more aggressively. The fresher E-M10 III will have an edge with regard to sensor innovation.
