I bought a very similar fujifilm camera a few years ago but ended up returning it simply because I was concerned that the permanent glass lens cover would get scratched up while living in the hipbelt pocket of my pack. I ended up getting an Olympis stylus tough (not sure if they still make it) which had a metal cover that automatically shut over the lens when the camera was off, that camera has served me well for several years.
If you do use the Fujifilm for a long hike I'd be interested to know afterwards whether the lack of a separate lens cover causes any problem or if I was just being paranoid about it.
