Canon R8 vs Olympus E-M5 III Sensor Comparison

Quite often, it can be difficult to picture the contrast in sensor sizing purely by looking through a spec sheet. The photograph here should provide you a more clear sense of the sensor dimensions in the R8 and E-M5 III.

Clearly, each of the cameras posses different resolutions and different sensor sizing. The R8 featuring a larger sensor is going to make getting bokeh simpler and the Canon R8 will result in extra detail as a result of its extra 4 Megapixels. Greater resolution will also let you crop images somewhat more aggressively. The younger R8 should have an advantage with regard to sensor tech.
