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 FujiFilm S2500HD and Panasonic G5 side-by-side from the front, back and top in their relative dimensions. FujiFilm S2500HD has external dimensions of 110 x 73 x 81 mm (4.33 x 2.89 x 3.19″) and weighs 337 g (0.74 lb / 11.89 oz) (including batteries). Panasonic G5 has external dimensions of 120 x 83 x 71 mm (4.72 x 3.27 x 2.8″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).
Below you can see the front view size comparison of FujiFilm S2500HD and Panasonic G5. FujiFilm S2500HD is 10mm narrower and 10mm shorter than Panasonic G5 but it is also 10mm thicker. As you can tell, actually this is not a fair size comparison since FujiFilm S2500HD has a built-in lens but Panasonic G5 doesn't. Once you put a lens on G5, its thickness will increase significantly.
Here is the back view size comparison of FujiFilm S2500HD and Panasonic G5.
Now lets look at the top view comparison of FujiFilm S2500HD and Panasonic G5.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
FujiFilm S2500HD is significantly lighter (59g ) than the Panasonic G5 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on G5, the total kit will weigh much higher.
Unfortunately neither FujiFilm FinePix S2500HD (FinePix S2600HD) nor Panasonic Lumix DMC-G5 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 S2500HD and Panasonic G5's LCD screens has the same diagonal size of 3.
On the other hand, Panasonic G5 sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. FujiFilm S2500HD's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G5.
