Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Panasonic XS1 and Olympus XZ-2 iHS side-by-side from the front, back and top in their relative dimensions. Panasonic XS1 has external dimensions of 94 x 54 x 14 mm (3.7 x 2.13 x 0.55″) and weighs 103 g (0.23 lb / 3.63 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic XS1 is significantly lighter (243g ) than the Olympus XZ-2 iHS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-XS1 nor Olympus XZ-2 iHS 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
Olympus XZ-2 iHS's 3.00" LCD screen is slightly larger than Panasonic XS1's 2.7" screen.
In addition to the size advantage, Olympus XZ-2 iHS 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 XZ-2 iHS.
