All in all, the two cameras enjoy different megapixels and different sensor sizing. The E-420 because of its smaller sensor will make getting bokeh more challenging and the Pentax K-1 will result in greater detail having its extra 26 Megapixels. Greater resolution will help you crop pics far more aggressively. The older E-420 will be disadvantaged when it comes to sensor technology.
