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 S1H and Canon R3 side-by-side from the front, back and top in their relative dimensions. Panasonic S1H has external dimensions of 151 x 114 x 110 mm (5.94 x 4.49 x 4.33″) and weighs 1052 g (2.32 lb / 37.11 oz) (including batteries). Canon R3 has external dimensions of 150 x 143 x 87 mm (5.91 x 5.63 x 3.43″) and weighs 1015 g (2.24 lb / 35.80 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic S1H and the Canon R3. Canon R3 is 1mm narrower and 23mm thinner than Panasonic S1H but it is also 29mm taller.
Here is the back view size comparison of the Panasonic S1H and Canon R3.
Now lets look at the top view comparison of Panasonic S1H and Canon R3.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon R3 is 37g lighter than the Panasonic S1H but we don't think this will make a significant difference.
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 S1H and Canon R3 have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Both the S1H and the R3 have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Panasonic S1H and Canon R3's LCD screens have the same diagonal size of 3.20 inches.
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 Selfies and video.
