Weather Sealing
Unfortunately neither the Casio Exilim EX-ZR300 nor Panasonic Lumix DC-ZS80 (Lumix DC-TZ95) 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-ZR300 and Panasonic ZS80's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic ZS80 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Casio EX-ZR300 has a fixed type screen which provides less flexibility in shooting positions compared to ZS80.
