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 G9 and Panasonic GX8 side-by-side from the front, back and top in their relative dimensions. Panasonic G9 has external dimensions of 137 x 97 x 92 mm (5.39 x 3.82 x 3.62″) and weighs 658 g (1.45 lb / 23.21 oz) (including batteries). Panasonic GX8 has external dimensions of 133 x 78 x 63 mm (5.24 x 3.07 x 2.48″) and weighs 487 g (1.07 lb / 17.18 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic G9 and the Panasonic GX8. Panasonic GX8 is clearly the smaller of the two cameras. Its body is 4mm narrower, 19mm shorter and 29mm thinner than Panasonic G9.
Here is the back view size comparison of the Panasonic G9 and Panasonic GX8.
Now lets look at the top view comparison of Panasonic G9 and Panasonic GX8.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GX8 is significantly lighter (171g ) than the Panasonic G9 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 both Panasonic G9 and Panasonic GX8 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 the G9 and the GX8 have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
