Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon S6100 and Samsung NX2000 side-by-side from the front, back and top in their relative dimensions. Nikon S6100 has external dimensions of 98 x 58 x 27 mm (3.86 x 2.28 x 1.06″) and weighs 175 g (0.39 lb / 6.17 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 Nikon S6100 and Samsung NX2000. Nikon S6100 is clearly the smaller of the two cameras. Its body is 21mm narrower, 7mm shorter and 9mm thinner than Samsung NX2000. As you can tell, actually this is not a fair size comparison since Nikon S6100 has a built-in lens but Samsung NX2000 doesn't. Once you put a lens on NX2000, its thickness will increase significantly.
Now lets look at the top view comparison of Nikon S6100 and Samsung NX2000.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon S6100 is significantly lighter (53g ) than the Samsung NX2000 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 NX2000, the total kit will weigh much higher.
Unfortunately neither Nikon Coolpix S6100 nor Samsung NX2000 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
