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 A7 II 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 A7 II has external dimensions of 127 x 96 x 60 mm (5 x 3.78 x 2.36″) and weighs 599 g (1.32 lb / 21.13 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-M5 III and the Sony A7 II. Olympus E-M5 III is clearly the smaller of the two cameras. Its body is 2mm narrower, 11mm shorter and 10mm thinner than Sony A7 II.
Here is the back view size comparison of the Olympus E-M5 III and Sony A7 II.
Now lets look at the top view comparison of Olympus E-M5 III and Sony A7 II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-M5 III is significantly lighter (185g ) than the Sony A7 II 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 A7 II has a Full frame 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 A7 II lenses.
Weather Sealing
Both the E-M5 Mark III and the A7 II have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Olympus E-M5 III and Sony A7 II's LCD screens have the same diagonal size of 3.00 inches.
Sony A7 II 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.
