Sometimes, it is very hard to envision the gap between sensor sizing simply by checking specs. The graphic here will provide you a far better sense of the sensor dimensions in the E-M10 and K-3 II.

As you can plainly see, the two cameras have got different megapixels and different sensor sizing. The E-M10 due to its tinier sensor will make getting shallower DOF more difficult and the Pentax K-3 II will resolve more detail as a result of its extra 8MP. Higher resolution can also make it easier to crop photographs much more aggressively. The older E-M10 is going to be behind with regard to sensor innovation.
