The E-M10 was brought out 4 years earlier than the GH5S and that is quite a sizable difference as far as tech is concerned. Each of these cameras have the same body design (SLR-style mirrorless).

Before we go right into a step-by-step comparison, here is a short highlight of how the E-M10 matches up vs the GH5S with respect to portability, imaging, features and an overall grade.

Oftentimes, it is very hard to visualize the gap between sensor measurements purely by checking a spec sheet. The graphic below may provide you a better sense of the sensor dimensions in the E-M10 and GH5S.

Clearly, both cameras provide the same sensor dimensions albeit different megapixels. You can expect the Olympus E-M10 to give extra detail having its extra 6MP. Higher resolution will also allow you to crop shots more aggressively. The older E-M10 is going to be behind in sensor technology.
