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 MIII and Leica Q side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon G7 X MIII is significantly lighter (336g ) than the Leica Q which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot G7 X Mark III nor Leica Q (Typ 116) 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 MIII features a Tilting screen
