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 S2800HD and Nikon P7800 side-by-side from the front, back and top in their relative dimensions. FujiFilm S2800HD has external dimensions of 110 x 74 x 82 mm (4.33 x 2.91 x 3.23″) and weighs 437 g (0.96 lb / 15.41 oz) (including batteries). Nikon P7800 has external dimensions of 119 x 78 x 50 mm (4.69 x 3.07 x 1.97″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries).
Below you can see the front view size comparison of FujiFilm S2800HD and Nikon P7800. FujiFilm S2800HD is 9mm narrower and 4mm shorter than Nikon P7800 but it is also 32mm thicker.
Here is the back view size comparison of FujiFilm S2800HD and Nikon P7800.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon P7800 is 38g lighter than the FujiFilm S2800HD but we don't think this will make a significant difference.
Unfortunately neither FujiFilm FinePix S2800HD (FinePix S2900HD) nor Nikon Coolpix P7800 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
FujiFilm S2800HD and Nikon P7800's LCD screens has the same diagonal size of 3".
On the other hand, Nikon P7800 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. FujiFilm S2800HD's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P7800.
