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 Galaxy NX and Samsung NX2000 side-by-side from the front, back and top in their relative dimensions. 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). Samsung NX2000 has external dimensions of 119 x 65 x 36 mm (4.69 x 2.56 x 1.42″) and weighs 228 g (0.50 lb / 8.04 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung Galaxy NX and the Samsung NX2000. Samsung NX2000 is 18mm narrower and 36mm shorter than Samsung Galaxy NX but it is also 10mm thicker.
Now lets look at the top view comparison of Samsung Galaxy NX and Samsung NX2000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung NX2000 is significantly lighter (267g ) than the Samsung Galaxy NX 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 both Samsung Galaxy NX and Samsung NX2000 have the same Samsung NX lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Samsung Galaxy NX nor Samsung NX2000 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
Samsung Galaxy NX's 4.80" LCD screen is slightly larger than Samsung NX2000's 3.7" screen.
