Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SX240 HS is 9g lighter than the Canon SX270 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither Canon PowerShot SX240 HS nor Canon PowerShot SX270 HS provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
