The E-M1 III was manufactured 5 years after the RX10 which is a fairly sizable difference as far as camera tech is concerned. Both of the cameras offer different body type with the Olympus E-M1 III being a SLR-style mirrorless camera and the Sony RX10 being a SLR-like (bridge) camera.

Before going straight into a detailed comparison, below is a short view of how the E-M1 III grades versus the RX10 with regards to portability, imaging, features and an overall mark.

Oftentimes, it is very tough to picture the gap in sensor dimensions purely by viewing specifications. The picture here will give you a stronger sense of the sensor dimensions in the E-M1 III and RX10.

Plainly, each of the cameras offer the same exact MP but different sensor dimensions. The E-M1 III has the larger sensor which will make achieving shallower depth of field less difficult. The younger E-M1 III should have an advantage in sensor innovation.
