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 A6000 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 A6000 has external dimensions of 120 x 67 x 45 mm (4.72 x 2.64 x 1.77″) and weighs 344 g (0.76 lb / 12.13 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-M5 III and the Sony A6000. Sony A6000 is clearly the smaller of the two cameras. Its body is 5mm narrower, 18mm shorter and 5mm thinner than Olympus E-M5 III.
Here is the back view size comparison of the Olympus E-M5 III and Sony A6000.
Now lets look at the top view comparison of Olympus E-M5 III and Sony A6000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6000 is significantly lighter (70g ) 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 A6000 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 A6000 lenses.
Weather Sealing
With its weather-sealed body, we believe that the E-M5 Mark III has a big advantage over the A6000 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Olympus E-M5 III and Sony A6000's LCD screens have the same diagonal size of 3.00 inches.
Sony A6000 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.
