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

Unfortunately neither Panasonic Lumix DC-ZS200 (Lumix DC-TZ200) 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.
