Canon R3 vs Olympus E-M5 III Sensor Comparison
More often than not, it is very tough to imagine the contrast between sensor sizes purely by checking specs. The picture here should give you a more clear sense of the sensor sizing in the R3 and E-M5 III.
As you can plainly see, both cameras provide different megapixels and different sensor sizes. The R3 using its larger sensor is going to make getting shallow depth of field less difficult and the Canon R3 will give you more detail having an extra 4 Megapixels. Greater resolution will also let you crop pics more aggressively. The fresher R3 should have an edge in sensor technology.
