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 Samsung NX200 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). Samsung NX200 has external dimensions of 117 x 63 x 36 mm (4.61 x 2.48 x 1.42″) and weighs 223 g (0.49 lb / 7.87 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic GF7 and the Samsung NX200. Panasonic GF7 is 10mm narrower and 3mm thinner than Samsung NX200 but it is also 2mm taller.
Now lets look at the top view comparison of Panasonic GF7 and Samsung NX200.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung NX200 is significantly lighter (43g ) than the Panasonic GF7 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 Samsung NX200 has an APS-C sized sensor and Panasonic GF7 has a smaller Four Thirds sensor, Panasonic GF7's lenses for a similar focal length and aperture will generally be lighter and smaller than the Samsung NX200 lenses.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-GF7 nor Samsung NX200 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 Samsung NX200'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 Samsung NX200 has a fixed type screen which provides less flexibility in shooting positions compared to GF7.
