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 FH1 and Olympus XZ-10 side-by-side from the front, back and top in their relative dimensions. Panasonic FH1 has external dimensions of 98 x 55 x 23 mm (3.86 x 2.17 x 0.91″) and weighs 163 g (0.36 lb / 5.75 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FH1 is significantly lighter (58g ) than the Olympus XZ-10 which may become a big advantage especially on long walking trips.
Unfortunately neither Panasonic Lumix DMC-FH1 (Lumix DMC-FS10) nor Olympus Stylus XZ-10 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Olympus XZ-10's 3" LCD screen is slightly larger than Panasonic FH1's 2.7" screen.
