Here is a detailed review of the Olympus E-PM1 and Pentax K-1 II, one being a Entry-Level Mirrorless and the latter is a Advanced DSLR by brands Olympus and Pentax. There is a significant difference among the sensor resolutions of the E-PM1 (12MP) and K-1 II (36MP) and the E-PM1 (Four Thirds) and K-1 II (Full frame) enjoy different sensor size.

The E-PM1 was introduced 7 years earlier than the K-1 II and that is a fairly sizable gap as far as camera tech is concerned. Both cameras offer different body type with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Pentax K-1 II being a Mid-size SLR camera.

Before we go straight into a detailed comparison, below is a simple highlight of how the E-PM1 scores versus the K-1 II with regards to portability, imaging, features and an overall rating.

Usually, it's tough to visualize the contrast in sensor sizing just by checking out specs. The visual here may give you a far better sense of the sensor dimensions in the E-PM1 and K-1 II.

As you can plainly see, both of these cameras enjoy different megapixel count and different sensor sizing. The E-PM1 with its smaller sensor is going to make shooting bokeh harder and the Pentax K-1 II will provide more detail using its extra 24MP. Higher resolution will also enable you to crop photographs far more aggressively. The older E-PM1 will be disadvantaged with regard to sensor technology.
