Pentax K-1 II vs Samsung GX-20 Sensor Comparison

Generally, it can be hard to imagine the difference between sensor dimensions simply by going over a spec sheet. The pic below will help offer you a far better sense of the sensor dimensions in the K-1 II and GX-20.

Clearly, both cameras offer different megapixels and different sensor dimensions. The K-1 II featuring a bigger sensor is going to make shooting shallow depth of field easier and the Pentax K-1 II will deliver more detail due to its extra 21 Megapixels. Higher resolution will make it easier to crop shots a little more aggressively. The more recent K-1 II should have a benefit in sensor technology.
