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 Panasonic GX9 and Olympus E-M5 III side-by-side from the front, back and top in their relative dimensions. Panasonic GX9 has external dimensions of 124 x 72 x 47 mm (4.88 x 2.83 x 1.85″) and weighs 450 g (0.99 lb / 14.36 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Panasonic GX9 and the Olympus E-M5 III. Panasonic GX9 is clearly the smaller of the two cameras. Its body is 1mm narrower, 13mm shorter and 3mm thinner than Olympus E-M5 III.
Here is the back view size comparison of the Panasonic GX9 and Olympus E-M5 III.
Now lets look at the top view comparison of Panasonic GX9 and Olympus E-M5 III.
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 36g lighter than the Panasonic GX9 but we don't think this will make a significant difference.
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 both Panasonic GX9 and Olympus E-M5 III have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Thanks to the weather-sealed body of the E-M5 Mark III, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the GX9.
LCD Screen Size and Features
Panasonic GX9 and Olympus E-M5 III's LCD screens have the same diagonal size of 3.00 inches.
Panasonic GX9 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.
