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 Nikon S6900 and Samsung GX-20 side-by-side from the front, back and top in their relative dimensions. Nikon S6900 has external dimensions of 99 x 58 x 28 mm (3.9 x 2.28 x 1.1″) and weighs 181 g (0.40 lb / 6.38 oz) (including batteries). Samsung GX-20 has external dimensions of 142 x 101 x 72 mm (5.59 x 3.98 x 2.83″) and weighs 800 g (1.76 lb / 28.22 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S6900 and the Samsung GX-20. Nikon S6900 is clearly the smaller of the two cameras. Its body is 43mm narrower, 43mm shorter and 44mm thinner than Samsung GX-20. As you can tell, actually this is not a fair size comparison since Nikon S6900 has a built-in lens but Samsung GX-20 doesn't. Once you put a lens on GX-20, its thickness will increase significantly.
Here is the back view size comparison of the Nikon S6900 and Samsung GX-20.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S6900 is significantly lighter (619g ) than the Samsung GX-20 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 GX-20, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the GX-20, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the S6900.
LCD Screen Size and Features
Nikon S6900's 3.00" LCD screen is slightly larger than Samsung GX-20's 2.7" screen.
Moreover, Nikon S6900 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Samsung GX-20 has a fixed type screen which provides almost no flexibility in shooting positions compared to S6900.
