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 G7 and Panasonic GH4 side-by-side from the front, back and top in their relative dimensions. Panasonic G7 has external dimensions of 125 x 86 x 77 mm (4.92 x 3.39 x 3.03″) and weighs 410 g (0.90 lb / 14.46 oz) (including batteries). Panasonic GH4 has external dimensions of 133 x 93 x 84 mm (5.24 x 3.66 x 3.31″) and weighs 560 g (1.23 lb / 19.75 oz) (including batteries).
Below you can see the front view size comparison of Panasonic G7 and Panasonic GH4. Panasonic G7 is clearly the smaller of the two cameras. Its body is 8mm narrower, 7mm shorter and 7mm thinner than Panasonic GH4.
Here is the back view size comparison of Panasonic G7 and Panasonic GH4.
Now lets look at the top view comparison of Panasonic G7 and Panasonic GH4.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic G7 is significantly lighter (150g ) than the Panasonic GH4 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 G7 and Panasonic GH4 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.
Thanks to the weather sealed body of GH4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to G7.
