Weather Sealing
Unfortunately neither the Casio Exilim EX-ZR1000 nor Panasonic Lumix DMC-ZS8 (Lumix DMC-TZ18) 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
Casio EX-ZR1000 and Panasonic ZS8's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Casio EX-ZR1000 features a
