Often, its difficult to visualize the contrast between sensor sizing simply by checking a spec sheet. The graphic underneath will help give you a far better sense of the sensor sizing in the E-M1 II and K10D.

Clearly, each of the cameras enjoy different megapixel count and different sensor sizing. The E-M1 II having a tinier sensor is going to make shooting shallow depth of field more difficult and the Olympus E-M1 II will give you extra detail because of its extra 10MP. Higher resolution will make it easier to crop shots far more aggressively. The newer E-M1 II provides an edge in sensor innovation.
