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 Fujifilm XQ1 nor Panasonic Lumix DMC-ZS50 (Lumix DMC-TZ70) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Fujifilm XQ1 and Panasonic ZS50's LCD screens have the same diagonal size of 3.00 inches.
