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 GF2 and Panasonic GF7 side-by-side from the front, back and top in their relative dimensions. Panasonic GF2 has external dimensions of 113 x 68 x 33 mm (4.45 x 2.68 x 1.3″) and weighs 310 g (0.68 lb / 10.93 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Panasonic GF2 and the Panasonic GF7. Panasonic GF7 is 6mm narrower and 3mm shorter than Panasonic GF2 but they have the same thickness of 33mm.
Here is the back view size comparison of the Panasonic GF2 and Panasonic GF7.
Now lets look at the top view comparison of Panasonic GF2 and Panasonic GF7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GF7 is significantly lighter (44g ) than the Panasonic GF2 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 GF2 and Panasonic GF7 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-GF2 nor Panasonic Lumix DMC-GF7 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 GF2 and Panasonic GF7's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic GF7 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Panasonic GF2 has a fixed type screen which provides less flexibility in shooting positions compared to GF7.
