Its time to look a little more in depth at the Olympus E-M1X and Pentax K100D, one being a Pro Mirrorless and the other is a Entry-Level DSLR by brands Olympus and Pentax. There exists a crucial gap among the sensor resolutions of the E-M1X (20MP) and K100D (6MP) and the E-M1X (Four Thirds) and K100D (APS-C) have totally different sensor sizes.

The E-M1X was brought out 12 years later than the K100D and that is a fairly serious gap as far as camera technology is concerned. Each of these cameras have different body design with the Olympus E-M1X being a SLR-style mirrorless camera and the Pentax K100D being a Compact SLR camera.

Before we go right into a complete comparison, here is a brief synopsis of how the E-M1X scores against the K100D in regards to portability, imaging, features and an overall rating.

More often than not, it is tough to envision the gap in sensor sizing only by seeing technical specs. The visual underneath will offer you a more clear sense of the sensor measurements in the E-M1X and K100D.

As you have seen, both of these cameras provide different resolutions and different sensor sizing. The E-M1X because of its smaller sensor will make achieving shallow DOF more challenging and the Olympus E-M1X will provide more detail having its extra 14MP. Greater resolution will allow you to crop images more aggressively. The more recent E-M1X will have an edge when it comes to sensor technology.
