Olympus 1s vs Pentax K-1 II Sensor Comparison

Generally, it is difficult to imagine the gap in sensor dimensions merely by checking out technical specs. The pic below may provide you a far better sense of the sensor dimensions in the 1s and K-1 II.

As you have seen, the two cameras come with different megapixels and different sensor dimensions. The 1s having a smaller sensor is going to make shooting shallow depth of field tougher and the Pentax K-1 II will produce greater detail with its extra 24 Megapixels. Higher resolution will let you crop photographs a good deal more aggressively. The more aged 1s will be behind when it comes to sensor technology.
