Olympus 1s vs Pentax K-70 Sensor Comparison

Typically, it's tough to visualise the contrast in sensor dimensions purely by seeing technical specs. The pic below will offer you a clearer sense of the sensor sizes in the 1s and K-70.

As you have seen, both of the cameras have got different resolutions and different sensor dimensions. The 1s featuring a smaller sensor will make shooting shallower DOF more difficult and the Pentax K-70 will provide more detail as a result of its extra 12MP. Higher resolution will allow you to crop shots much more aggressively. The more aged 1s will be disadvantaged with regard to sensor tech.
