Sometimes, its difficult to see the contrast in sensor dimensions just by viewing specs. The picture here will give you a clearer sense of the sensor dimensions in the E-M1 III and GX7.
As you can plainly see, the two cameras enjoy the same exact sensor sizing but not the same resolution. You can anticipate the Olympus E-M1 III to render extra detail because of its extra 4MP.
