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 G100 and Sony ZV-E10 side-by-side from the front, back and top in their relative dimensions. Panasonic G100 has external dimensions of 116 x 83 x 54 mm (4.57 x 3.27 x 2.13″) and weighs 352 g (0.78 lb / 12.42 oz) (including batteries). Sony ZV-E10 has external dimensions of 115 x 64 x 45 mm (4.53 x 2.52 x 1.77″) and weighs 343 g (0.76 lb / 12.10 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic G100 and the Sony ZV-E10. Sony ZV-E10 is clearly the smaller of the two cameras. Its body is 1mm narrower, 19mm shorter and 9mm thinner than Panasonic G100.
Here is the back view size comparison of the Panasonic G100 and Sony ZV-E10.
Now lets look at the top view comparison of Panasonic G100 and Sony ZV-E10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony ZV-E10 is 9g lighter than the Panasonic G100 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 Sony ZV-E10 has an APS-C sized sensor and Panasonic G100 has a smaller Four Thirds sensor, Panasonic G100's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony ZV-E10 lenses.
Weather Sealing
Unfortunately neither the Panasonic Lumix DC-G100 nor Sony ZV-E10 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic G100 and Sony ZV-E10's LCD screens have the same diagonal size of 3.00 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.
