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 Leica Digilux 3 and Panasonic L1 side-by-side from the front, back and top in their relative dimensions. Leica Digilux 3 has external dimensions of 146 x 87 x 77 mm (5.75 x 3.43 x 3.03″) and weighs 606 g (1.34 lb / 21.38 oz) (including batteries). Panasonic L1 has external dimensions of 146 x 87 x 77 mm (5.75 x 3.43 x 3.03″) and weighs 606 g (1.34 lb / 21.38 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica Digilux 3 and Panasonic L1 have exactly the same weight of 606g.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Leica Digilux 3 and Panasonic L1 have the same Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Leica Digilux 3 nor Panasonic Lumix DMC-L1 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
Leica Digilux 3 and Panasonic L1's LCD screens have the same diagonal size of 2.50 inches.
