Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor FujiFilm FinePix Z700EXR (FinePix Z707EXR) 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 Z700EXR's 3.5" LCD screen is slightly larger than Panasonic ZS3's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
