Size and weight are big decision factors when you are trying to find the ideal camera for your needs.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 350 HS (IXUS 275 HS) nor Leica Q (Typ 116) 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
Canon ELPH 350 HS and Leica Q's LCD screens have the same diagonal size of 3.00 inches.
