Olympus E-M1X vs Pentax K-70 Sensor Comparison

Normally, it is very tough to visualise the contrast in sensor measurements merely by researching a spec sheet. The visual here may provide you a clearer sense of the sensor dimensions in the E-M1X and K-70.

As you can see, each of the cameras offer different megapixels and different sensor measurements. The E-M1X with its smaller sensor will make getting shallow depth of field more difficult and the Pentax K-70 will render greater detail having an extra 4MP. Greater resolution will allow you to crop pics a little more aggressively. The more modern E-M1X is going to have an edge in sensor technology.
