Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the FujiFilm FinePix S4000 (FinePix S4050) nor Olympus SZ-12 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
