Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS35 (Lumix DMC-TZ55) nor Panasonic Lumix DMC-ZS40 (Lumix DMC-TZ60) 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
Panasonic ZS35 and Panasonic ZS40's LCD screens have the same diagonal size of 3.00 inches.

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 Panasonic ZS40 has a fixed type screen which provides less flexibility in shooting positions compared to ZS35.
