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

Unfortunately neither the Sony Cyber-shot DSC-WX50 nor Olympus SP-620 UZ provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
