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 Samsung MV800 and Panasonic GH4 side-by-side from the front, back and top in their relative dimensions. Samsung MV800 has external dimensions of 92 x 56 x 10 mm (3.62 x 2.21 x 0.41″) and weighs 121 g (0.27 lb / 4.27 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 the Samsung MV800 and the Panasonic GH4. Samsung MV800 is clearly the smaller of the two cameras. Its body is 41mm narrower, 37mm shorter and 74mm thinner than Panasonic GH4. As you can tell, actually this is not a fair size comparison since Samsung MV800 has a built-in lens but Panasonic GH4 doesn't. Once you put a lens on GH4, its thickness will increase significantly.
Now lets look at the top view comparison of Samsung MV800 and Panasonic GH4.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung MV800 is significantly lighter (439g ) than the Panasonic GH4 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on GH4, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the GH4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the MV800.
LCD Screen Size and Features
Samsung MV800 and Panasonic GH4's LCD screens have the same diagonal size of 3.00 inches.
Samsung MV800 features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Panasonic GH4 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
