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 FujiFilm S2500HD and Canon A800 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). Canon A800 has external dimensions of 94 x 61 x 31 mm (3.7 x 2.4 x 1.22″) and weighs 186 g (0.41 lb / 6.56 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A800 is significantly lighter (151g ) than the FujiFilm S2500HD which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the FujiFilm FinePix S2500HD (FinePix S2600HD) nor Canon PowerShot A800 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
FujiFilm S2500HD's 3.00" LCD screen is slightly larger than Canon A800's 2.5" screen.
