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 FujiFilm S2500HD and Nikon 1 V1 side-by-side from the front, back and top in their relative dimensions. FujiFilm S2500HD has external dimensions of 110 x 73 x 81 mm (4.33 x 2.89 x 3.19″) and weighs 337 g (0.74 lb / 11.89 oz) (including batteries). Nikon 1 V1 has external dimensions of 113 x 76 x 44 mm (4.45 x 2.99 x 1.71″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries).
Below you can see the front view size comparison of FujiFilm S2500HD and Nikon 1 V1. FujiFilm S2500HD is 3mm narrower and 3mm shorter than Nikon 1 V1 but it is also 37mm thicker. As you can tell, actually this is not a fair size comparison since FujiFilm S2500HD has a built-in lens but Nikon 1 V1 doesn't. Once you put a lens on 1 V1, 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.
FujiFilm S2500HD is 46g lighter than the Nikon 1 V1 but we don't think this will make a significant difference.
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 1 V1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither FujiFilm FinePix S2500HD (FinePix S2600HD) nor Nikon 1 V1 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
