The 645Z was introduced 4 years prior to the K-1 II and that is a fairly sizable difference as far as camera technology is concerned. The two cameras have different body design with the Pentax 645Z being a Large SLR camera and the Pentax K-1 II being a Mid-size SLR camera.

Before delving into a step-by-step comparison, here is a simple introduction of how the 645Z scores against the K-1 II in regards to portability, imaging, features and an overall rating.

Remember that, the weight of an ILC will change based on the lens you are using at that time. Below is a front view over all size comparison of the 645Z versus the K-1 II.

Taking into consideration dimensions and weight, the portability grade of the 645Z and K-1 II is 49 and 55 respectively.

Typically, it's difficult to imagine the difference in sensor sizing only by seeing specifications. The photograph here may offer you a much better sense of the sensor dimensions in the 645Z and K-1 II.

Plainly, the 2 cameras have different megapixel count and different sensor sizing. The 645Z with its bigger sensor is going to make getting shallower depth of field less difficult and the Pentax 645Z will produce extra detail using its extra 15 Megapixels. Higher resolution can also make it easier to crop shots a bit more aggressively. The older 645Z will be disadvantaged in sensor technology.
