Always remember, the weight of an Interchangeable Lens Camera will differ based on the lens you are utilising during that time. Here is a front view measurement comparison of the E-M5 III against the G900.

Factoring in dimensions and weight, the portability rating of the E-M5 III and G900 is 80 and 89 respectively.

Normally, it can be difficult to visualize the difference in sensor measurements just by viewing technical specs. The photograph below should give you a much better sense of the sensor sizes in the E-M5 III and G900.

As you can tell, both the cameras provide the same megapixel count albeit different sensor measurements. The E-M5 III has the bigger sensor which is going to make achieving shallower DOF less difficult. The newer E-M5 III should have a benefit with regard to sensor innovation.
