Fujifilm GFX 100S vs Olympus E-M1 Sensor Comparison

		

		

			
Quite often, its tough to envision the gap in sensor dimensions merely by viewing a spec sheet. The picture here will help offer you a clearer sense of the sensor sizing in the Fujifilm GFX 100S and E-M1.
As you can see, both of the cameras have different megapixel count and different sensor dimensions. The Fujifilm GFX 100S using its larger sensor will make shooting bokeh simpler and the Fujifilm GFX 100S will render more detail with its extra 86 Megapixels. Greater resolution will make it easier to crop photos a bit more aggressively. The more recent Fujifilm GFX 100S is going to have an edge with regard to sensor tech.
