Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic GH5 and Olympus E-M1X side-by-side from the front, back and top in their relative dimensions. Panasonic GH5 has external dimensions of 139 x 98 x 87 mm (5.47 x 3.86 x 3.43″) and weighs 725 g (1.60 lb / 25.57 oz) (including batteries). Olympus E-M1X has external dimensions of 144 x 147 x 75 mm (5.67 x 5.79 x 2.95″) and weighs 997 g (2.20 lb / 35.17 oz) (including batteries).
Below you can see the front view size comparison of Panasonic GH5 and Olympus E-M1X. Panasonic GH5 is 5mm narrower and 49mm shorter than Olympus E-M1X but it is also 12mm thicker.
Here is the back view size comparison of Panasonic GH5 and Olympus E-M1X.
Now lets look at the top view comparison of Panasonic GH5 and Olympus E-M1X.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic GH5 is significantly lighter (272g ) than the Olympus E-M1X 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 have to also take into account the lenses that you will be using with these bodies. Since both Panasonic GH5 and Olympus E-M1X 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.
Both GH5 and E-M1X have weather sealings in their body, making them resistant to water and dust.
