Olympus E-M10 IV vs Pentax K-1 II Sensor Comparison

Plainly, the 2 cameras have different megapixels and different sensor sizes. The E-M10 IV featuring a tinier sensor is going to make achieving shallow depth of field more challenging and the Pentax K-1 II will offer you more detail having its extra 16 Megapixels. Greater resolution can also enable you to crop images a bit more aggressively. The younger E-M10 IV provides a benefit with regard to sensor technology.
