Olympus E-1 vs Pentax K-1 II Sensor Comparison

Quite often, it is very tough to envision the gap between sensor sizing only by reading through technical specs. The visual below should give you a far better sense of the sensor sizing in the E-1 and K-1 II.

As you have seen, both cameras come with different megapixel count and different sensor sizing. The E-1 because of its tinier sensor will make getting bokeh more challenging and the Pentax K-1 II will give more detail having its extra 31 Megapixels. Greater resolution can also enable you to crop pics a good deal more aggressively. The older E-1 is going to be behind when it comes to sensor tech.
