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 Olympus 1 side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus 1 is 35g lighter than the FujiFilm S2800HD but we don't think this will make a significant difference.
Unfortunately neither FujiFilm FinePix S2800HD (FinePix S2900HD) nor Olympus Stylus 1 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 Olympus 1's LCD screens has the same diagonal size of 3".
On the other hand, Olympus 1 features a Tilting screen
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the FujiFilm S2800HD has a fixed type screen which provides less flexibility in shooting positions compared to 1.
