Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Olympus E-M5 III and Sony NEX-3N side-by-side from the front, back and top in their relative dimensions. Olympus E-M5 III has external dimensions of 125 x 85 x 50 mm (4.92 x 3.35 x 1.97″) and weighs 414 g (0.91 lb / 14.60 oz) (including batteries). Sony NEX-3N has external dimensions of 110 x 62 x 35 mm (4.33 x 2.44 x 1.38″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-M5 III and the Sony NEX-3N. Sony NEX-3N is clearly the smaller of the two cameras. Its body is 15mm narrower, 23mm shorter and 15mm thinner than Olympus E-M5 III.
Here is the back view size comparison of the Olympus E-M5 III and Sony NEX-3N.
Now lets look at the top view comparison of Olympus E-M5 III and Sony NEX-3N.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony NEX-3N is significantly lighter (145g ) than the Olympus E-M5 III which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since Sony NEX-3N has an APS-C sized sensor and Olympus E-M5 III has a smaller Four Thirds sensor, Olympus E-M5 III's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony NEX-3N lenses.
Weather Sealing
With its weather-sealed body, we believe that the E-M5 Mark III has a big advantage over the NEX-3N which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Olympus E-M5 III and Sony NEX-3N's LCD screens have the same diagonal size of 3.00 inches.
Sony NEX-3N features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Olympus E-M5 III sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
