Olympus E-M5 II vs Sony A9 II Sensor Comparison

Usually, it can be tough to picture the difference in sensor sizes merely by going through specifications. The pic below will provide you a much better sense of the sensor measurements in the E-M5 II and A9 II.

Plainly, the 2 cameras have got different megapixels and different sensor sizes. The E-M5 II featuring a smaller sensor is going to make shooting shallow depth of field harder and the Sony A9 II will show more detail as a result of its extra 8MP. Greater resolution can also enable you to crop images much more aggressively. The more aged E-M5 II will be disadvantaged with regard to sensor innovation.
