Pentax K-5 vs YI M1

Following is a comprehensive comparison of the Pentax K-5 versus YI M1, one is a Advanced DSLR and the latter is a Entry-Level Mirrorless by brands Pentax and YI. The sensor resolution of the K-5 (16MP) and the M1 (20MP) is relatively well matched but the K-5 (APS-C) and M1 (Four Thirds) use different sensor measurements.

The K-5 was brought out 6 years prior to the M1 which is quite a sizable gap as far as technology is concerned. Both of the cameras offer different body type with the Pentax K-5 being a Mid-size SLR camera and the YI M1 being a Rangefinder-style mirrorless camera.

Before we go straight into a step-by-step comparison, below is a quick view of how the K-5 grades versus the M1 in the way of portability, imaging, features and an overall score.

The following is a preview of the gallery photos for Pentax K-5 and YI M1. The entire galleries are available at Pentax K-5 Gallery and YI M1 Gallery.

If you're planning to carry around your camera frequently, you will have to think about its weight and size.

Remember that, the weight of an Interchangeable Lens Camera will vary dependant on the lens you are using at the time. Underneath is the front view measurements comparison of the K-5 versus the M1.

Looking at dimensions and weight, the portability grade of the K-5 and M1 is 60 and 87 respectively.

More often than not, it's hard to visualize the gap between sensor sizes merely by reading through technical specs. The image below will offer you a greater sense of the sensor sizing in the K-5 and M1.

As you have seen, both of the cameras offer different megapixels and different sensor sizes. The K-5 due to its bigger sensor is going to make getting shallow depth of field simpler and the YI M1 will give greater detail having its extra 4MP. Higher resolution can also make it easier to crop shots a little more aggressively. The more aged K-5 is going to be disadvantaged in sensor tech.
