Olympus E-M5 III vs Sony NEX-5 Sensor Comparison

Normally, it is difficult to see the gap in sensor measurements purely by going through a spec sheet. The photograph below will help give you a more clear sense of the sensor dimensions in the E-M5 III and NEX-5.

Clearly, the two cameras enjoy different resolutions and different sensor measurements. The E-M5 III due to its smaller sensor will make achieving shallow depth of field more difficult and the Olympus E-M5 III will show greater detail as a result of its extra 6 Megapixels. Higher resolution will also enable you to crop photographs far more aggressively. The newer E-M5 III is going to have an edge when it comes to sensor innovation.
