Olympus E-M1 III vs Sony A6300 Sensor Comparison

		

		

			
More often than not, it's tough to see the contrast in sensor measurements simply by going through technical specs. The visual here should give you a stronger sense of the sensor measurements in the E-M1 III and A6300.
As you can tell, both of those cameras provide different megapixels and different sensor measurements. The E-M1 III using its smaller sensor will make achieving shallow depth of field more challenging and the Sony A6300 will show more detail because of its extra 4 Megapixels. Greater resolution will let you crop images more aggressively. The more recent E-M1 III is going to have an advantage when it comes to sensor tech.
