As you can tell, both of these cameras provide different resolutions and different sensor measurements. The K-1 II due to its bigger sensor will make shooting shallower depth of field simpler and the Pentax K-1 II will result in more detail due to its extra 22MP. Higher resolution can also help you crop shots more aggressively. The more modern K-1 II will have an edge when it comes to sensor innovation.
