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-XS1 nor Panasonic Lumix DMC-ZS70 (Lumix DC-TZ90) 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 ZS70's 3.00" LCD screen is slightly larger than Panasonic XS1's 2.7" screen.
In addition to the size advantage, Panasonic ZS70 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Panasonic XS1 has a fixed type screen which provides less flexibility in shooting positions compared to ZS70.
