The E-M10 III was introduced 4 years later than the K-30 and that is quite a serious gap as far as technology is concerned. Both of the cameras have different body design with the Olympus E-M10 III being a SLR-style mirrorless camera and the Pentax K-30 being a Mid-size SLR camera.

Before delving straight to a comprehensive comparison, here is a brief view of how the E-M10 III grades vs the K-30 for portability, imaging, features and an overall rating.

Quite often, it's hard to imagine the contrast between sensor sizing purely by reading through a spec sheet. The graphic here should give you a far better sense of the sensor measurements in the E-M10 III and K-30.

As you can see, each of these cameras provide the same megapixels but different sensor sizing. The E-M10 III includes the tinier sensor which will make obtaining shallower depth of field tougher. The younger E-M10 III should have a benefit when it comes to sensor tech.
