Olympus E-M1 III vs Panasonic GH5S Sensor Comparison

		

		

			
Oftentimes, it is very tough to envision the contrast between sensor measurements only by reviewing specs. The photograph here will help provide you a greater sense of the sensor measurements in the E-M1 III and GH5S.
As you can plainly see, both the cameras have got the exact same sensor measurements but not the same resolution. You can anticipate the Olympus E-M1 III to deliver more detail as a result of its extra 10 Megapixels. Greater resolution will also let you crop photos much more aggressively. The newer E-M1 III is going to have an edge in sensor innovation.
