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 G9 and Fujifilm S1 side-by-side from the front, back and top in their relative dimensions. Panasonic G9 has external dimensions of 137 x 97 x 92 mm (5.39 x 3.82 x 3.62″) and weighs 658 g (1.45 lb / 23.21 oz) (including batteries). Fujifilm S1 has external dimensions of 133 x 91 x 110 mm (5.24 x 3.58 x 4.33″) and weighs 680 g (1.50 lb / 23.99 oz) (including batteries).
Below you can see the front view size comparison of Panasonic G9 and Fujifilm S1. Fujifilm S1 is 4mm narrower and 6mm shorter than Panasonic G9 but it is also 18mm thicker. As you can tell, actually this is not a fair size comparison since Fujifilm S1 has a built-in lens but Panasonic G9 doesn't. Once you put a lens on G9, its thickness will increase significantly.
Here is the back view size comparison of Panasonic G9 and Fujifilm S1.
Now lets look at the top view comparison of Panasonic G9 and Fujifilm S1.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic G9 is 22g lighter than the Fujifilm S1 but we don't think this will make a significant difference.
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 G9, the total kit will weigh much higher.
Both G9 and S1 have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Panasonic G9 and Fujifilm S1's LCD screens has the same diagonal size of 3".
Both cameras feature Fully Articulating screens
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. Fully articulating screens are also useful for taking Selfie shots and video.
