The K-1 was unveiled 7 months earlier than the M1 so they are both of a similar generation. Each of these cameras have different body design with the Pentax K-1 being a Mid-size SLR camera and the YI M1 being a Rangefinder-style mirrorless camera.

Before diving straight to a thorough comparison, here is a quick highlight of how the K-1 matches up vs the M1 with regards to portability, imaging, features and an overall grade.

Below is a sample of the gallery pictures for Pentax K-1 and YI M1. The full galleries are viewable at Pentax K-1 Gallery and YI M1 Gallery.

In many cases, it is very hard to imagine the contrast in sensor measurements purely by viewing a spec sheet. The graphic here will offer you a better sense of the sensor sizing in the K-1 and M1.

As you can see, the 2 cameras have different resolutions and different sensor measurements. The K-1 using its larger sensor is going to make achieving shallow DOF less difficult and the Pentax K-1 will render extra detail having an extra 16MP. Greater resolution can also make it easier to crop images a bit more aggressively. The older K-1 will be behind when it comes to sensor tech.
