To sum up, the 2 cameras feature different megapixels and different sensor measurements. The E-M10 III using its smaller sensor is going to make shooting bokeh harder and the Pentax K-S2 will provide greater detail with its extra 4MP. Higher resolution can also make it easier to crop pictures way more aggressively. The more recent E-M10 III provides a benefit when it comes to sensor innovation.
