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 Casio EX-Z450 and FujiFilm JV100 side-by-side from the front, back and top in their relative dimensions. Casio EX-Z450 has external dimensions of 81 x 56 x 21 mm (3.19 x 2.2 x 0.83″) and weighs 128 g (0.28 lb / 4.52 oz) (including batteries). FujiFilm JV100 has external dimensions of 93 x 55 x 21 mm (3.66 x 2.17 x 0.83″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries).
Below you can see the front-view size comparison of the Casio EX-Z450 and the FujiFilm JV100.
Here is the back view size comparison of the Casio EX-Z450 and FujiFilm JV100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
FujiFilm JV100 is 2g lighter than the Casio EX-Z450 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Casio Exilim EX-Z450 nor FujiFilm FinePix JV100 (FinePix JV105) 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
Casio EX-Z450's 3.00" LCD screen is slightly larger than FujiFilm JV100's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
