Usually, it's tough to visualize the contrast in sensor sizing just by checking out specs. The visual here may give you a far better sense of the sensor dimensions in the E-PM1 and K-1 II.

As you can plainly see, both of these cameras enjoy different megapixel count and different sensor sizing. The E-PM1 with its smaller sensor is going to make shooting bokeh harder and the Pentax K-1 II will provide more detail using its extra 24MP. Higher resolution will also enable you to crop photographs far more aggressively. The older E-PM1 will be disadvantaged with regard to sensor technology.
