The E-M1 III was announced 6 years after the RX1R which is quite a large gap as far as technology is concerned. Both of these cameras feature different body design with the Olympus E-M1 III being a SLR-style mirrorless camera and the Sony RX1R being a Large Sensor Compact camera.

Before delving right into a in-depth comparison, here is a short summation of how the E-M1 III scores against the RX1R in relation to portability, imaging, features and an overall score.

Following is a sample of the gallery pictures for Olympus OM-D E-M1 Mark III and Sony Cyber-shot DSC-RX1R. The whole galleries are provided at Olympus E-M1 III Gallery and Sony RX1R Gallery.

Quite often, its difficult to envision the gap between sensor sizes just by looking at specifications. The image underneath might offer you a far better sense of the sensor sizes in the E-M1 III and RX1R.

Plainly, each of the cameras come with different resolutions and different sensor sizes. The E-M1 III using its tinier sensor will make achieving shallow depth of field harder and the Sony RX1R will give extra detail with its extra 4 Megapixels. Greater resolution will also allow you to crop images a good deal more aggressively. The more recent E-M1 III is going to have an edge with regard to sensor technology.
