Olympus E-M10 IV vs Panasonic S1 Sensor Comparison

		

		

			
Usually, its hard to see the contrast in sensor measurements only by researching technical specs. The graphic underneath should provide you a far better sense of the sensor dimensions in the E-M10 IV and S1.
As you can tell, each of these cameras come with different megapixels and different sensor measurements. The E-M10 IV due to its smaller sensor will make shooting shallower depth of field trickier and the Panasonic S1 will render more detail as a result of its extra 4 Megapixels. Higher resolution will help you crop pictures a good deal more aggressively. The more modern E-M10 IV will have an advantage in sensor technology.
