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 Sony A7 III and Samsung Galaxy NX side-by-side from the front, back and top in their relative dimensions. Sony A7 III has external dimensions of 127 x 96 x 74 mm (5 x 3.78 x 2.91″) and weighs 650 g (1.43 lb / 22.93 oz) (including batteries). Samsung Galaxy NX has external dimensions of 137 x 101 x 26 mm (5.39 x 3.98 x 1.02″) and weighs 495 g (1.09 lb / 17.46 oz) (including batteries).
Below you can see the front-view size comparison of the Sony A7 III and the Samsung Galaxy NX. Sony A7 III is 10mm narrower and 5mm shorter than Samsung Galaxy NX but it is also 48mm thicker.
Here is the back view size comparison of the Sony A7 III and Samsung Galaxy NX.
Now lets look at the top view comparison of Sony A7 III and Samsung Galaxy NX.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung Galaxy NX is significantly lighter (155g ) than the Sony A7 III 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 Sony A7 III has a Full frame sensor and Samsung Galaxy NX has a smaller APS-C sensor, Samsung Galaxy NX's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7 III lenses.
Weather Sealing
With its weather-sealed body, we believe that the A7 III has a big advantage over the Galaxy NX which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Samsung Galaxy NX's 4.80" LCD screen is slightly larger than Sony A7 III's 3″ screen.
On the other hand, Sony A7 III LCD screen has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Samsung Galaxy NX has a fixed type screen which provides less flexibility in shooting positions compared to A7 III.
