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 Nikon P340 and Panasonic FH2 side-by-side from the front, back and top in their relative dimensions. Nikon P340 has external dimensions of 103 x 58 x 32 mm (4.06 x 2.28 x 1.26″) and weighs 194 g (0.43 lb / 6.84 oz) (including batteries). Panasonic FH2 has external dimensions of 94 x 54 x 19 mm (3.7 x 2.13 x 0.75″) and weighs 121 g (0.27 lb / 4.27 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon P340 and the Panasonic FH2. Panasonic FH2 is clearly the smaller of the two cameras. Its body is 9mm narrower, 4mm shorter and 13mm thinner than Nikon P340.
Here is the back view size comparison of the Nikon P340 and Panasonic FH2.
Now lets look at the top view comparison of Nikon P340 and Panasonic FH2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FH2 is significantly lighter (73g ) than the Nikon P340 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix P340 nor Panasonic Lumix DMC-FH2 (Lumix DMC-FS16) 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
Nikon P340's 3.00" LCD screen is slightly larger than Panasonic FH2's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
