The K-01 was revealed 5 years earlier than the M1 which is a fairly big gap as far as camera tech is concerned. Both cameras come with different body type with the Pentax K-01 being a SLR-style mirrorless camera and the YI M1 being a Rangefinder-style mirrorless camera.

Before delving in to a complete comparison, below is a quick synopsis of how the K-01 grades against the M1 when it comes to portability, imaging, features and an overall score.

Here is a preview of the gallery images for Pentax K-01 and YI M1. The full galleries are viewable at Pentax K-01 Gallery and YI M1 Gallery.

In case you're planning to carry around your camera frequently, you are going to need to factor in its weight and volume.

Take into consideration, the weight of an Interchangeable Lens Camera will differ depending on the lens you have chosen at that moment. The following is the front view physical size comparison of the K-01 compared to the M1.

Factoring in size and weight, the portability rating of the K-01 and M1 is 76 and 87 respectively.

Often, it can be tough to imagine the difference in sensor sizes merely by viewing specifications. The picture underneath will give you a stronger sense of the sensor sizing in the K-01 and M1.

Plainly, both of these cameras posses different resolutions and different sensor sizes. The K-01 using its bigger sensor is going to make achieving shallow depth of field easier and the YI M1 will provide you with greater detail because of its extra 4 Megapixels. Higher resolution can also allow you to crop pictures somewhat more aggressively. The more aged K-01 will be behind with regard to sensor tech.
