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 Canon G5 X and Panasonic FH5 side-by-side from the front, back and top in their relative dimensions. Canon G5 X has external dimensions of 112 x 76 x 44 mm (4.41 x 2.99 x 1.73″) and weighs 353 g (0.78 lb / 12.45 oz) (including batteries). Panasonic FH5 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 Canon G5 X and Panasonic FH5. Panasonic FH5 is clearly the smaller of the two cameras. Its body is 18mm narrower, 22mm shorter and 25mm thinner than Canon G5 X.
Here is the back view size comparison of Canon G5 X and Panasonic FH5.
Now lets look at the top view comparison of Canon G5 X and Panasonic FH5.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FH5 is significantly lighter (232g ) than the Canon G5 X which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot G5 X nor Panasonic Lumix DMC-FH5 (Lumix DMC-FS18) 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
Canon G5 X's 3" LCD screen is slightly larger than Panasonic FH5's 2.7" screen.
Moreover, Canon G5 X 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. On the other hand, Panasonic FH5 has a fixed type screen which provides almost no flexibility in shooting positions compared to G5 X.
