Olympus E-M10 III vs Sony NEX-3N

In this article, we will be contrasting the Olympus E-M10 III vs Sony NEX-3N, both Entry-Level Mirrorless cameras by companies Olympus and Sony. The resolution of the E-M10 III (16MP) and the NEX-3N (16MP) is pretty comparable but the E-M10 III (Four Thirds) and NEX-3N (APS-C) use totally different sensor measurements.

The E-M10 III was launched 4 years later than the NEX-3N and that is a fairly big difference as far as camera technology is concerned. Both cameras offer different body type with the Olympus E-M10 III being a SLR-style mirrorless camera and the Sony NEX-3N being a Rangefinder-style mirrorless camera.

Before delving through a more detailed comparison, below is a quick highlight of how the E-M10 III scores against the NEX-3N in regards to portability, imaging, features and an overall grade.

Quite often, it's difficult to visualise the contrast in sensor measurements just by going through a spec sheet. The photograph below will help give you a better sense of the sensor measurements in the E-M10 III and NEX-3N.

Clearly, both of these cameras enjoy the same exact megapixels albeit not the same sensor measurements. The E-M10 III uses the smaller sensor which will make achieving shallower DOF more challenging. The more modern E-M10 III is going to have an advantage in sensor innovation.
