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 S5 and Canon G5 X side-by-side from the front, back and top in their relative dimensions. Panasonic S5 has external dimensions of 133 x 97 x 82 mm (5.24 x 3.82 x 3.23″) and weighs 714 g (1.57 lb) (including batteries). 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).
Below you can see the front view size comparison of Panasonic S5 and Canon G5 X. Canon G5 X is clearly the smaller of the two cameras. Its body is 21mm narrower, 21mm shorter and 38mm thinner than Panasonic S5. As you can tell, actually this is not a fair size comparison since Canon G5 X has a built-in lens but Panasonic S5 doesn't. Once you put a lens on S5, its thickness will increase significantly.
Here is the back view size comparison of Panasonic S5 and Canon G5 X.
Now lets look at the top view comparison of Panasonic S5 and Canon G5 X.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon G5 X is significantly lighter (361g ) than the Panasonic S5 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 S5, the total kit will weigh much higher.
With its weather sealed body, we believe that S5 has a big advantage over G5 X which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
