Olympus E-M1 vs Sony RX10 III

Here, we are contrasting the Olympus E-M1 and Sony RX10 III, one is a Pro Mirrorless and the other is a Large Sensor Superzoom by competitors Olympus and Sony. The sensor resolution of the E-M1 (16MP) and the RX10 III (20MP) is very comparable but the E-M1 (Four Thirds) and RX10 III (1") provide totally different sensor size.

The E-M1 was manufactured 3 years prior to the RX10 III which is a fairly large gap as far as camera tech is concerned. Both the cameras feature different body design with the Olympus E-M1 being a SLR-style mirrorless camera and the Sony RX10 III being a SLR-like (bridge) camera.

Before delving straight to a more detailed comparison, here is a quick summary of how the E-M1 grades against the RX10 III when considering portability, imaging, features and an overall score.

Remember, the weight of an Interchangeable Lens Camera will vary based on the lens you are utilising at the time. Below is a front view sizing comparison of the E-M1 and the RX10 III.

Taking into consideration size and weight, the portability grade of the E-M1 and RX10 III is 71 and 53 respectively.

In many cases, it's difficult to see the gap in sensor sizes merely by seeing technical specs. The picture below will offer you a much better sense of the sensor dimensions in the E-M1 and RX10 III.

As you have seen, both of the cameras feature different megapixel count and different sensor sizes. The E-M1 due to its larger sensor will make achieving shallow depth of field easier and the Sony RX10 III will produce extra detail due to its extra 4 Megapixels. Greater resolution will also make it easier to crop pics way more aggressively. The more aged E-M1 will be behind in sensor technology.
