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 FujiFilm AX350 and Panasonic ZS8 side-by-side from the front, back and top in their relative dimensions. FujiFilm AX350 has external dimensions of 93 x 60 x 28 mm (3.66 x 2.36 x 1.1″) and weighs 168 g (0.37 lb / 5.93 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
FujiFilm AX350 is significantly lighter (42g ) than the Panasonic ZS8 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the FujiFilm FinePix AX350 (FinePix AX355) nor Panasonic Lumix DMC-ZS8 (Lumix DMC-TZ18) 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
Panasonic ZS8's 3.00" LCD screen is slightly larger than FujiFilm AX350's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
