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 Panasonic ZS7 and FujiFilm JZ500 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS7 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
FujiFilm JZ500 is significantly lighter (50g ) than the Panasonic ZS7 which may become a big advantage especially on long walking trips.
Unfortunately neither Panasonic Lumix DMC-ZS7 (Lumix DMC-TZ10) nor FujiFilm FinePix JZ500 (FinePix JZ505) 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
Panasonic ZS7's 3" LCD screen is slightly larger than FujiFilm JZ500's 2.7 screen.
