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 Pentax X90 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). Pentax X90 has external dimensions of 111 x 85 x 110 mm (4.37 x 3.35 x 4.33″) and weighs 428 g (0.94 lb / 15.10 oz) (including batteries).
Below you can see the front-view size comparison of the FujiFilm S2800HD and the Pentax X90. FujiFilm S2800HD is clearly the smaller of the two cameras. Its body is 1mm narrower, 11mm shorter and 28mm thinner than Pentax X90.
Here is the back view size comparison of the FujiFilm S2800HD and Pentax X90.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax X90 is 9g lighter than the FujiFilm S2800HD but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the FujiFilm FinePix S2800HD (FinePix S2900HD) nor Pentax X90 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 S2800HD's 3.00" LCD screen is slightly larger than Pentax X90's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
