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 GF7 and Panasonic GX850 side-by-side from the front, back and top in their relative dimensions. Panasonic GF7 has external dimensions of 107 x 65 x 33 mm (4.21 x 2.56 x 1.3″) and weighs 266 g (0.59 lb / 9.38 oz) (including batteries). Panasonic GX850 has external dimensions of 107 x 65 x 33 mm (4.21 x 2.56 x 1.3″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic GF7 and the Panasonic GX850. In this case, we can see that Panasonic GF7 and Panasonic GX850 have the exact same height, width and thickness.
Here is the back view size comparison of the Panasonic GF7 and Panasonic GX850.
Now lets look at the top view comparison of Panasonic GF7 and Panasonic GX850.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GF7 is 3g lighter than the Panasonic GX850 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 GF7 and Panasonic GX850 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
Unfortunately neither the Panasonic Lumix DMC-GF7 nor Panasonic Lumix DMC-GX850 (Lumix DMC-GX800 / Lumix DMC-GF9) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic GF7 and Panasonic GX850's LCD screens have the same diagonal size of 3.00 inches.

Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
