Olympus E-PL1s vs Pentax K-1 II Sensor Comparison

Normally, it is very difficult to imagine the contrast between sensor sizing purely by looking at a spec sheet. The visual underneath should offer you a much better sense of the sensor measurements in the E-PL1s and K-1 II.

As you can see, both of these cameras posses different megapixel count and different sensor sizing. The E-PL1s using its tinier sensor is going to make shooting shallow depth of field more difficult and the Pentax K-1 II will give extra detail with its extra 24 Megapixels. Greater resolution will help you crop photos somewhat more aggressively. The older E-PL1s is going to be disadvantaged in sensor technology.
