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 Olympus Stylus SH-3 nor Canon PowerShot SX520 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
