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 Sony Cyber-shot DSC-W620 nor Canon PowerShot G16 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G16's 3.00" LCD screen is slightly larger than Sony W620's 2.7" screen.
