Olympus E-M1 III vs Sony NEX-3N

Let's look more closely at the Olympus E-M1 III vs Sony NEX-3N, one being a Pro Mirrorless and the latter is a Entry-Level Mirrorless by rivals Olympus and Sony. There is a big difference between the resolutions of the E-M1 III (20MP) and NEX-3N (16MP) and the E-M1 III (Four Thirds) and NEX-3N (APS-C) boast different sensor measurements.

Photography Glossary

The E-M1 III was manufactured 7 years later than the NEX-3N and that is quite a big gap as far as tech is concerned. The two cameras have different body design with the Olympus E-M1 III being a SLR-style mirrorless camera and the Sony NEX-3N being a Rangefinder-style mirrorless camera.

Before going straight to a more detailed comparison, here is a brief highlight of how the E-M1 III scores vs the NEX-3N in regards to portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Olympus OM-D E-M1 Mark III and Sony Alpha NEX-3N. The entire galleries are provided at Olympus E-M1 III Gallery and Sony NEX-3N Gallery.

When you are looking to lug around your camera frequently, you will want to take into account its weight and size.

Using size and weight, the portability score of the E-M1 III and NEX-3N is 67 and 89 respectively.

Often, its difficult to visualize the contrast between sensor measurements only by going over technical specs. The graphic below may offer you a stronger sense of the sensor dimensions in the E-M1 III and NEX-3N.

As you have seen, both cameras have different megapixel count and different sensor measurements. The E-M1 III due to its tinier sensor is going to make shooting shallower depth of field more difficult and the Olympus E-M1 III will offer extra detail due to its extra 4MP. Higher resolution will make it easier to crop shots a bit more aggressively. The more recent E-M1 III should have a benefit in sensor tech.
