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 Panasonic S5 II and Panasonic S1 side-by-side from the front, back and top in their relative dimensions. Panasonic S5 II has external dimensions of 134 x 102 x 90 mm (5.29 x 4.03 x 3.55″) and weighs 740 g (1.63 lb / 26.10 oz) (including batteries). Panasonic S1 has external dimensions of 149 x 110 x 97 mm (5.87 x 4.33 x 3.82″) and weighs 1021 g (2.25 lb) (including batteries).
Below you can see the front-view size comparison of the Panasonic S5 II and the Panasonic S1. Panasonic S5 II is clearly the smaller of the two cameras. Its body is 15mm narrower, 8mm shorter and 7mm thinner than Panasonic S1.
Here is the back view size comparison of the Panasonic S5 II and Panasonic S1.
Now lets look at the top view comparison of Panasonic S5 II and Panasonic S1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic S5 II is significantly lighter (281g ) than the Panasonic S1 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Panasonic S5 II and Panasonic S1 have the same Leica L lens mount and Full frame sized sensors, lenses will not be a differentiator on total size of the system.
Both the S5 Mark II and the S1 have weather sealings in their bodies, making them resistant to water and dust.
