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 Canon G7 X MII and Panasonic ZS100 side-by-side from the front, back and top in their relative dimensions. Canon G7 X MII has external dimensions of 106 x 61 x 42 mm (4.17 x 2.4 x 1.65″) and weighs 319 g (0.70 lb / 11.25 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS100 is 7g lighter than the Canon G7 X MII but we don't think this will make a significant difference.
Unfortunately neither Canon PowerShot G7 X Mark II nor Panasonic Lumix DMC-ZS100 (Lumix DMC-TZ100) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

On the other hand, Canon G7 X MII features a Tilting screen
