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 A99 and Samsung Galaxy NX side-by-side from the front, back and top in their relative dimensions. Sony A99 has external dimensions of 147 x 111 x 78 mm (5.79 x 4.37 x 3.07″) and weighs 812 g (1.79 lb / 28.64 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 A99 and the Samsung Galaxy NX. Samsung Galaxy NX is clearly the smaller of the two cameras. Its body is 10mm narrower, 10mm shorter and 52mm thinner than Sony A99.
Now lets look at the top view comparison of Sony A99 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 (317g ) than the Sony A99 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 A99 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 A99 lenses.
Weather Sealing
With its weather-sealed body, we believe that the A99 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 A99's 3 screen.
On the other hand, Sony A99 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 Galaxy NX has a fixed type screen which provides almost no flexibility in shooting positions compared to A99.
