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 Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor Leica D-LUX 5 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Panasonic ZS3 and Leica D-LUX 5's LCD screens have the same diagonal size of 3.00 inches.
