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 S2800HD and Olympus SP-810 UZ 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). Olympus SP-810 UZ has external dimensions of 106 x 76 x 74 mm (4.17 x 2.99 x 2.91″) and weighs 413 g (0.91 lb / 14.57 oz) (including batteries).
Below you can see the front-view size comparison of the FujiFilm S2800HD and the Olympus SP-810 UZ. Olympus SP-810 UZ is 4mm narrower and 8mm thinner than FujiFilm S2800HD but it is also 2mm taller.
Here is the back view size comparison of the FujiFilm S2800HD and Olympus SP-810 UZ.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SP-810 UZ is 24g lighter than the FujiFilm S2800HD but we don't think this will make a significant difference.

Unfortunately neither the FujiFilm FinePix S2800HD (FinePix S2900HD) nor Olympus SP-810 UZ provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
