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 SX420 IS nor Panasonic Lumix DC-FZ80D (Lumix DC-FZ82D / Lumix DC-FZ85D) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Canon SX420 IS and Panasonic FZ80D's LCD screens have the same diagonal size of 3.00 inches.
