Olympus E-M1 II vs Sony A7 III

Let's examine more in depth at the Olympus E-M1 II versus Sony A7 III, both Pro Mirrorless cameras by competitors Olympus and Sony. The sensor resolution of the E-M1 II (20MP) and the A7 III (24MP) is fairly close but the E-M1 II (Four Thirds) and A7 III (Full frame) use different sensor size.

The E-M1 II was unveiled 17 months earlier than the A7 III making the cameras a generation apart from each other. Both of these cameras offer the identical body type (SLR-style mirrorless).

Before diving through a full comparison, below is a quick synopsis of how the E-M1 II grades versus the A7 III when considering portability, imaging, features and an overall grade.

This is a sample of the gallery pictures for Olympus OM-D E-M1 Mark II & Sony Alpha A7 III. The full galleries are available at Olympus E-M1 II Gallery & Sony A7 III Gallery.

If you are planning to lug around your camera, you should factor its weight and volume. The Olympus E-M1 II has got external dimensions of 134mm x 91mm x 67mm (5.3" x 3.6" x 2.6") accompanied by a weight of 574 grams (1.27 lbs) whilst the Sony A7 III has sizing of 127mm x 96mm x 74mm (5.0" x 3.8" x 2.9") with a weight of 650 grams (1.43 lbs).

Bear in mind, the weight of an ILC will change based on the lens you are utilising at the time. Here is the front view dimensions comparison of the E-M1 II and the A7 III.

Factoring in size and weight, the portability grade of the E-M1 II and A7 III is 68 and 63 respectively.

Oftentimes, it can be hard to visualize the contrast in sensor measurements merely by looking through specifications. The graphic here should give you a much better sense of the sensor dimensions in the E-M1 II and A7 III.

To sum up, both the cameras enjoy different resolutions and different sensor measurements. The E-M1 II having a smaller sensor is going to make getting shallower DOF harder and the Sony A7 III will provide you with more detail having an extra 4MP. Greater resolution will also make it easier to crop pics far more aggressively. The older E-M1 II will be behind in sensor innovation.
