Pentax K-1 II vs Pentax K-3 Sensor Comparison

Typically, its tough to visualise the difference in sensor sizing only by viewing a spec sheet. The visual underneath will help offer you a far better sense of the sensor dimensions in the K-1 II and K-3.

As you can see, the 2 cameras enjoy different resolutions and different sensor sizing. The K-1 II with its bigger sensor will make achieving shallower DOF less difficult and the Pentax K-1 II will render more detail because of its extra 12 Megapixels. Higher resolution will also let you crop photographs far more aggressively. The newer K-1 II will have a benefit when it comes to sensor technology.
