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

Weather Sealing
Unfortunately neither Sony Cyber-shot DSC-W710 nor Panasonic Lumix DMC-ZS40 (Lumix DMC-TZ60) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Panasonic ZS40's 3" LCD screen is slightly larger than Sony W710's 2.7" screen.
