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

Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS7 (Lumix DMC-TZ10) nor Sony Cyber-shot DSC-WX80 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Panasonic ZS7's 3" LCD screen is slightly larger than Sony WX80's 2.7" screen.
