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 FujiFilm S2950 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). FujiFilm S2950 has external dimensions of 110 x 73 x 81 mm (4.33 x 2.87 x 3.19″) and weighs 437 g (0.96 lb / 15.41 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L31 and the FujiFilm S2950. Nikon L31 is clearly the smaller of the two cameras. Its body is 14mm narrower, 14mm shorter and 52mm thinner than FujiFilm S2950.
Now lets look at the top view comparison of Nikon L31 and FujiFilm S2950.
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 (277g ) than the FujiFilm S2950 which may become a big advantage especially on long walking trips.
Unfortunately neither the Nikon Coolpix L31 nor FujiFilm FinePix S2950 (FinePix S2990) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

FujiFilm S2950's 3.00" LCD screen is slightly larger than Nikon L31's 2.7" screen.
