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 Olympus E-M1X 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). Olympus E-M1X has external dimensions of 144 x 147 x 75 mm (5.67 x 5.79 x 2.95″) and weighs 997 g (2.20 lb / 35.17 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic S1H and the Olympus E-M1X. Olympus E-M1X is 7mm narrower and 35mm thinner than Panasonic S1H but it is also 33mm taller.
Here is the back view size comparison of the Panasonic S1H and Olympus E-M1X.
Now lets look at the top view comparison of Panasonic S1H and Olympus E-M1X.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-M1X is 55g 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 Panasonic S1H has a Full frame sensor and Olympus E-M1X has a smaller Four Thirds sensor, Olympus E-M1X's lenses for a similar focal length and aperture will generally be lighter and smaller than the Panasonic S1H lenses.
Weather Sealing
Both the S1H and the E-M1X have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Panasonic S1H's 3.20" LCD screen is slightly larger than Olympus E-M1X's 3 screen.
