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 L31 and Samsung NX30 side-by-side from the front, back and top in their relative dimensions. Nikon L31 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Samsung NX30 has external dimensions of 127 x 96 x 58 mm (5 x 3.78 x 2.28″) and weighs 375 g (0.83 lb / 13.23 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L31 and the Samsung NX30. Nikon L31 is clearly the smaller of the two cameras. Its body is 31mm narrower, 37mm shorter and 29mm thinner than Samsung NX30. As you can tell, actually this is not a fair size comparison since Nikon L31 has a built-in lens but Samsung NX30 doesn't. Once you put a lens on NX30, its thickness will increase significantly.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is significantly lighter (215g ) than the Samsung NX30 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 NX30, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Nikon Coolpix L31 nor Samsung NX30 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 NX30's 3.00" LCD screen is slightly larger than Nikon L31's 2.7" screen.
Moreover, Samsung NX30 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, Nikon L31 has a fixed type screen which provides almost no flexibility in shooting positions compared to NX30.
