Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS100 is 28g lighter than the Panasonic ZS200 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither Panasonic Lumix DC-ZS200 (Lumix DC-TZ200) nor Panasonic Lumix DMC-ZS100 (Lumix DMC-TZ100) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
