Olympus E-M1X vs Sony A7R II

Here, we will be reviewing the Olympus E-M1X and Sony A7R II, both Pro Mirrorless digital cameras by rivals Olympus and Sony. There is a big difference between the sensor resolutions of the E-M1X (20MP) and A7R II (42MP) and the E-M1X (Four Thirds) and A7R II (Full frame) boast different sensor sizes.

The E-M1X was revealed 3 years later than the A7R II and that is quite a big gap as far as tech is concerned. Both the cameras feature the same body design (SLR-style mirrorless).

Before going straight to a complete comparison, here is a quick synopsis of how the E-M1X grades against the A7R II in regards to portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Olympus OM-D E-M1X and Sony Alpha A7R II. The full galleries are viewable at Olympus E-M1X Gallery and Sony A7R II Gallery.

If you are looking to lug around your camera frequently, you'll need to think about its weight and volume. The Olympus E-M1X enjoys exterior measurements of 144mm x 147mm x 75mm (5.7" x 5.8" x 3.0") and a weight of 997 grams (2.20 lbs) whilst the Sony A7R II has sizing of 127mm x 96mm x 60mm (5.0" x 3.8" x 2.4") accompanied by a weight of 625 grams (1.38 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will change dependant on the lens you use during that time. The following is a front view physical size comparison of the E-M1X compared to the A7R II.

Taking into account size and weight, the portability score of the E-M1X and A7R II is 54 and 68 respectively.

Usually, it is difficult to picture the contrast between sensor measurements purely by looking at technical specs. The graphic below will help give you a far better sense of the sensor sizing in the E-M1X and A7R II.

As you have seen, both of the cameras come with different megapixel count and different sensor measurements. The E-M1X having a tinier sensor is going to make getting shallower DOF harder and the Sony A7R II will give you more detail because of its extra 22MP. Higher resolution will help you crop pictures a good deal more aggressively. The fresher E-M1X should have an edge in sensor tech.
