Olympus E-M5 III vs Panasonic S1 Sensor Comparison

		

		

			
In many cases, it is very hard to visualise the contrast between sensor dimensions simply by going over specifications. The picture underneath will help offer you a greater sense of the sensor sizing in the E-M5 III and S1.
To sum up, each of these cameras posses different megapixels and different sensor dimensions. The E-M5 III having a tinier sensor will make shooting shallower depth of field more challenging and the Panasonic S1 will offer you more detail having an extra 4MP. Higher resolution will also let you crop pictures somewhat more aggressively. The newer E-M5 III will have a benefit when it comes to sensor tech.
