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

Unfortunately neither the Samsung TL225 (ST550) nor Panasonic Lumix DMC-FZ150 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
