Olympus E-M1 II vs Pentax K-5 Sensor Comparison

Normally, it is tough to visualize the gap between sensor sizing merely by checking a spec sheet. The visual underneath might offer you a clearer sense of the sensor measurements in the E-M1 II and K-5.

Clearly, both of the cameras have got different resolutions and different sensor sizing. The E-M1 II because of its tinier sensor is going to make achieving shallow depth of field more challenging and the Olympus E-M1 II will resolve more detail having its extra 4 Megapixels. Greater resolution can also make it easier to crop pics much more aggressively. The fresher E-M1 II should have an edge with regard to sensor innovation.
